e5e54f312b iscsi-scst: Move old TM response dropping to preparing new response stage 
The second TM request can come while the old one, response for which is
going to be delayed, is still being processed, hence no response
prepared yet, so the delayed response should be dropped on the stage of
the new response preparing. Otherwise in this place the old delayed
response will trigger BUG_ON().

760b71423a scst: Remove set_cpus_allowed() invocations

b6f2a47ee8 Change BUG_ON(1) into BUG() 
With CONFIG_BUG=y both BUG() and BUG_ON(1) halt the system. However,
with CONFIG_BUG=n BUG() halts the system but BUG_ON(1) not. To avoid
such subtleties, change BUG_ON(1) into BUG().

See also patch Josh Triplett, "bug: Make BUG() always stop the machine",
7 April 2014 (commit ID a4b5d580e07875f9be29f62a57c67fbbdbb40ba2).

daa5da87af Several wait loops in the SCST source code are similar. Move the common code 
into a new macro called wait_event_locked().

Signed-off-by: Bart Van Assche <bvanassche@acm.org>

+

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.
