Kashyap Desai 1635eb05c3 RDMA/bnxt_re: Avoid calling wake_up threads from spin_lock context 
[ Upstream commit 3099bcdc19 ]

bnxt_qplib_service_creq can be called from interrupt or tasklet or
process context. So the function take irq variant  of spin_lock.
But when wake_up is invoked with the lock held, it is putting the
calling context to sleep.

Call the wakeup after releasing the lock.
