lockd: Use xdrgen XDR functions for the NLMv3 TEST_RES procedure
Continue the xdrgen migration by converting NLMv3 TEST_RES,
the callback that a remote NLM uses to return async TEST
results to this lockd. The procedure now uses
nlm_svc_decode_nlm_testres and nlm_svc_encode_void, generated
from the NLM version 3 protocol specification.
Setting pc_argzero to zero is safe because the generated
decoder fills the argp->xdrgen subfields before the procedure
runs, so the zeroing memset performed by the dispatch layer
is no longer needed.
Setting pc_xdrressize to XDR_void reflects that TEST_RES, as
a callback, returns no data; the previous value of St
over-reserved a status word in the reply buffer.
