qlcnic: Fix a sleep-in-atomic bug in qlcnic_82xx_hw_write_wx_2M and qlcnic_82xx_hw_read_wx_2M
The driver may sleep under a write spin lock, and the function call path is: qlcnic_82xx_hw_write_wx_2M (acquire the lock by write_lock_irqsave) crb_win_lock qlcnic_pcie_sem_lock usleep_range qlcnic_82xx_hw_read_wx_2M (acquire the lock by write_lock_irqsave) crb_win_lock qlcnic_pcie_sem_lock usleep_range To fix it, the usleep_range is replaced with udelay.
