When receiving NLM_GRANTED_RES or NLM4_GRANTED_RES lock granted messages
from the NFS server, following contention on a lock by this or another
client, immediately notify the waiting process that the lock has been
granted via a wakeup. Without this change, the client rpc.lockd will
not wakeup the waiting process until it next re-polls the lock (sometime
in the next ten seconds), which can lead to marked latency across all
potential lockers, as the lock is held by the client for the duration.
