IB/cm: Fix sleeping while spin lock is held
In case of LAP are used for RoCE, it can lead to a problem of sleeping a
context while spin lock is held in below flow.
cm_lap_handler
->spin_lock
-> <..switch_case..>
-> cm_init_av_for_response
-> ib_init_ah_from_wc
-> rdma_addr_find_l2_eth_by_grh
wait_for_completion()
Therefore ah attribute initialization is done for incoming lap requests
outside of the lock context.
