lockd: Use xdrgen XDR functions for the NLMv4 LOCK_RES procedure

Browse Source 
Convert the LOCK_RES procedure to use xdrgen functions
nlm4_svc_decode_nlm4_res and nlm4_svc_encode_void.
LOCK_RES is a callback procedure where the client sends
lock results back to the server after an async LOCK
request.

The pc_argzero field is set to zero because xdrgen decoders
reliably initialize all arguments, making the early
defensive memset unnecessary.

This change also corrects the pc_xdrressize field, which
previously contained a placeholder value.
