NFSv4: Fix an incorrect parameter when calling nfs4_call_sync()

Browse source

[ Upstream commit 1f214e9c3a ]

The Smatch static checker noted that in _nfs4_proc_lookupp(), the flag
RPC_TASK_TIMEOUT is being passed as an argument to nfs4_init_sequence(),
which is clearly incorrect.
Since LOOKUPP is an idempotent operation, nfs4_init_sequence() should
not ask the server to cache the result. The RPC_TASK_TIMEOUT flag needs
to be passed down to the RPC layer.
