Since CQs are active\nduring the QP destroy, driver may still schedule completion\nhandlers. This can cause a race where the destroy_cq and poll_cq\nrunning simultaneously.\n\nSnippet of kernel panic while doing bnxt_re driver load unload in loop.\nThis indicates a poll after the CQ is freed. \n\n[77786.481636] Call Trace:\n[77786.481640]  <TASK>\n[77786.481644]  bnxt_re_poll_cq+0x14a/0x620 [bnxt_re]\n[77786.481658]  ? kvm_clock_read+0x14/0x30\n[77786.481693]  __ib_process_cq+0x57/0x190 [ib_core]\n[77786.481728]  ib_cq_poll_work+0x26/0x80 [ib_core]\n[77786.481761]  process_one_work+0x1e5/0x3f0\n[77786.481768]  worker_thread+0x50/0x3a0\n[77786.481785]  ? __pfx_worker_thread+0x10/0x10\n[77786.481790]  kthread+0xe2/0x110\n[77786.481794]  ? __pfx_kthread+0x10/0x10\n[77786.481797]  ret_from_fork+0x2c/0x50\n\nTo avoid this, complete all completion handlers before returning the\ndestroy QP.
