Fix two race conditions that could trigger this failure:
- Completion thread not woken up after channel state change.
- Reception of Last WQE event before the channel queue pair was reset.

Modified patch from Bart Van Assche <bvanassche@acm.org>:
The range unmapped by the scst_vdisk handler when processing an UNMAP command
is not correct. The patch below fixes that and also prevents that the following
kernel crash can be triggered on the target:

Invoking truncate_range() with an end len that is not page-size aligned
triggers it. In other words, with a block size that is below
PAGE_CACHE_SIZE some UNMAP commands could trigger a kernel bug. I think
it's better to print an error message and to skip an UNMAP command
instead of triggering a kernel oops.

The implementation of many tracing macros in scst_debug.h (like TRACE_DBG)
requires that at least one more argument must be provided in addition to format
which in some cases is an overkill. This patch fixes the issue and also unifies
macro signatures for the cases when CONFIG_SCST_DEBUG is either on or off.

scstadmin: Multiple -write_config bug fixes.
Bug fixes:
- Do not write out the line "# Non-key attributes" for the top level if -nonkey
has not been specified.
- If -nonkey has been specified, write out the device handler creation time
attributes too (blocksize, o_direct, read_only, removable, ...).
- If -nonkey has been specified, write out the LUN creation time attributes
too (read_only).
Also, simplify the -write_config implementation by introducing the Perl
subroutines serializeKeyAttr() and serializeNkAttr().

With NPIV initiators being destroyed and recreated, the loop_id and/or
the d_id of a virtual initiator may change. The current implementation not
always catches these changes, which leads to wrong virtual devices
being presented to the initiators. This can lead to i.e. corruption of LUN
content and multiple initiators writing to the same LUN, although the
LUN's access group only contains a single port.
Until a better solution is found, we schedule a session deletion for the
nexus when receiving an ELS port logout message. That way SCST
will re-initialize both loop_id and d_id when the initiator reconnects
before the actual deletion takes place. The performance impact is
minimal (few milliseconds) and currently necessary.

Several wait loops in the SCST source code are similar. Move the common code

Micro-optimize wait_event_locked(). Switch from default_wake_function() to
autoremove_wake_function() (via DEFINE_WAIT()). The result is that
wait_queue_head_t.lock is locked once instead of twice for wakeup + wait queue
removal.
