scsi: lpfc: Check return status of lpfc_reset_flush_io_context during TGT_RESET

Browse source 
[ Upstream commit f408dde2468b3957e92b25e7438f74c8e9fb9e73 ]

If lpfc_reset_flush_io_context fails to execute, then the wrong return
status code may be passed back to upper layers when issuing a target
reset TMF command.  Fix by checking the return status from
lpfc_reset_flush_io_context() first in order to properly return FAILED
or FAST_IO_FAIL.
