Junxiao Bi 233ac38916 qlcnic: fix deadlock bug ... The following soft lockup was caught. This is a deadlock caused by recusive locking. Process kworker/u40:1:28016 was holding spin lock "mbx->queue_lock" in qlcnic_83xx_mailbox_worker(), while a softirq came in and ask the same spin lock in qlcnic_83xx_enqueue_mbx_cmd().
