Maurizio Lombardi f6fe0b2d35 nvme-pci: fix sleeping function called from interrupt context 
the nvme_handle_cqe() interrupt handler calls nvme_complete_async_event()
but the latter may call nvme_auth_stop() which is a blocking function.
Sleeping functions can't be called in interrupt context

 BUG: sleeping function called from invalid context
 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 0, name: swapper/15
  Call Trace:
     <IRQ>
      __cancel_work_timer+0x31e/0x460
      ? nvme_change_ctrl_state+0xcf/0x3c0 [nvme_core]
      ? nvme_change_ctrl_state+0xcf/0x3c0 [nvme_core]
      nvme_complete_async_event+0x365/0x480 [nvme_core]
      nvme_poll_cq+0x262/0xe50 [nvme]

Fix the bug by moving nvme_auth_stop() to fw_act_work
(executed by the nvme_wq workqueue)
