[SCSI] qla2xxx: Correct use-after-free issue in terminate_rport_io callback.

The explicit logout (LOGO) issued at the end of the callback will
flush (via normal scsi_cmnd->done()) any outstanding commands
(FCP2) the firmware is holding.  While iterating through the
outstanding_cmnd array in qla2x00_abort_fcport_cmds(), locking
and unlocking of the hardware spinlock, opens-up the driver to
cases where the processed SRB (sp) could be used after the
command completed from interrupt context.
