scsi: fnic: Replace return codes in fnic_clean_pending_aborts()

fnic_clean_pending_aborts() was returning a non-zero value irrespective of
failure or success.  This caused the caller of this function to assume that
the device reset had failed, even though it would succeed in most cases. As
a consequence, a successful device reset would escalate to host reset.
