Chengchang Tang 979f4d58ca RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled 
[ Upstream commit 74d315b5af180220d561684d15897730135733a6 ]

Fix missuse of spin_lock_irq()/spin_unlock_irq() when
spin_lock_irqsave()/spin_lock_irqrestore() was hold.

This was discovered through the lock debugging, and the corresponding
log is as follows:

raw_local_irq_restore() called with IRQs enabled
WARNING: CPU: 96 PID: 2074 at kernel/locking/irqflag-debug.c:10 warn_bogus_irq_restore+0x30/0x40
