Chuck Lever e4c0565c98 NFSD: Clean up splice actor 
[ Upstream commit c7e0b781b73c2e26e442ed71397cc2bc5945a732 ]

A few useful observations:

 - The value in @size is never modified.

 - splice_desc.len is an unsigned int, and so is xdr_buf.page_len.
   An implicit cast to size_t is unnecessary.

 - The computation of .page_len is the same in all three arms
   of the "if" statement, so hoist it out to make it clear that
   the operation is an unconditional invariant.

The resulting function is 18 bytes shorter on my system (-Os).
