scsi: qla2xxx: Fix smatch warning in qla25xx_delete_{rsp|req}_que

commit 62aa281470fdb7c0796d63a1cc918a8c1f02dde2 upstream.

This patch fixes following warnings reported by smatch:

drivers/scsi/qla2xxx/qla_mid.c:586 qla25xx_delete_req_que()
error: we previously assumed 'req' could be null (see line 580)

drivers/scsi/qla2xxx/qla_mid.c:602 qla25xx_delete_rsp_que()
error: we previously assumed 'rsp' could be null (see line 596)
