[PATCH for-next] IB/srp: Make SCSI error handling finish

[Bart Van Assche]

If a SCSI command times out it is passed to the SCSI error
handler. The SCSI error handler keeps trying to abort a
command until aborting succeeded or the command has been
finished. Avoid that attempts to abort a command without
RDMA RC connection trigger an endless loop.
