dlm: Use sendmsg(MSG_SPLICE_PAGES) rather than sendpage
When transmitting data, call down a layer using a single sendmsg with
MSG_SPLICE_PAGES to indicate that content should be spliced rather using
sendpage. This allows ->sendpage() to be replaced by something that can
handle multiple multipage folios in a single transaction.
