RDMA/nes: Fix incorrect unlock in nes_process_mac_intr()
Commit ce6e74f2 ("RDMA/nes: Make nesadapter->phy_lock usage
consistent") introduced a problem where phy_lock was only unlocked
within an if statement and so nes_process_mac_intr() could return with
phy_lock still held. Fix this.
This was discovered because of the sparse warning:
drivers/infiniband/hw/nes/nes_hw.c:2643:9: warning: context imbalance in 'nes_process_mac_intr' - different lock contexts for basic block
