Fix the following failure:
# scstadmin -resync_dev volume01
Collecting current configuration: done.
-> Making requested changes.
-> WARNING: Device 'volume01' lacks the settable attribute 'resync_size', ignoring.
-> Done.
All done.
This patch fixes a regression that was introduced by r8171 (commit
aedcfc5997 ("scstadmin: Avoid that Perl complains about undefined values
for write-only attributes") # v3.4.

The scst_user device handler allocates its own data buffers. If ib_srpt
uses zero-copy mode, copy data as required between the device handler and
zero-copy buffer.

Remove these callback functions because:
- Since the introduction of the 'active' attribute, these callback functions
are no longer essential. See also commit 9d21169f8c ("scst: implement
BLOCKIO devices "active" attribute").
- The current implementation may break I/O. The following ALUA configuration
is sufficient to break I/O (because a remote group with state 'standby'
occurs last):
DEVICE_GROUP dgroup1 {
DEVICE disk01
TARGET_GROUP tgroup1 {
group_id 256
preferred 1
state active
TARGET scst_local_tgt
}
TARGET_GROUP tgroup2 {
group_id 257
state standby
TARGET scst_local_tgt_remote {
rel_tgt_id 7
}
}
}

Submitting an unaligned buffer is a bug. Additionally, the patch that added
support for unaligned buffers negatively affected performance of the ib_srpt
and scst_local drivers.
This patch reverts 85f8ac3a1e ("vdisk_blockio: Add support for unaligned
buffers").

Instead of only interpreting the empty string as "no argument passed", also
consider 'undef' as "no argument passed".

Support for autogenerated target names was declared obsolete in 2011. Remove
support for autogenerated target names. See also commit 21d503cbb7
("Autogenerated SCST target names made deprecated").
