splice: don't call file_accessed in copy_splice_read
[ Upstream commit 0b24be4691c9e6ea13ca70050d42a9f9032fa788 ]
copy_splice_read calls into ->read_iter to read the data, which already
calls file_accessed.
Fixes: 33b3b041543e ("splice: Add a func to do a splice from an O_DIRECT file without ITER_PIPE")
