[ 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.
