When we left off with READ_PLUS, Chuck had suggested reverting the
server to reply with a single NFS4_CONTENT_DATA segment essentially
mimicing how the READ operation behaves. Then, a future sparse read
function can be added and the server modified to support it without
needing to rip out the old READ_PLUS code at the same time.

This patch takes that first step. I was even able to re-use the
nfsd4_encode_readv() and nfsd4_encode_splice_read() functions to
remove some duuplicate code.

- v2:
  - Add splice read support
  - Address Chuck's style comments
  - Reword the commit message

Thanks,
Anna
