IB/mlx4: Fix value of pkey_index in QP1 completions
Fix the value of pkey_index in completions to get a valid value for
GSI QPs. Without this fix, incoming GSI packets on port 2 get an
invalid P_Key index in the completion, which prevents the MAD layer
from sending back a response, which can make the second port of
ConnectX HCAs completely useless.
