[PATCH 17/36] scsi: hpsa: Prepare for enabling lock context analysis

[Bart Van Assche <bvanassche@acm.org>]

mutex_lock_interruptible() returns a negative value upon failure or zero
upon success. Since the Clang thread-safety analyzer only supports == 0
and != 0 tests for functions that perform conditional locking, change
the == -EINTR test into != 0. This change does not modify the behavior
of hpsa_do_reset().
