xfs: Provide a splice-read wrapper
Provide a splice_read wrapper for XFS. This does a stat count and a
shutdown check before proceeding, then emits a new trace line and locks the
inode across the call to filemap_splice_read() and adds to the stats
afterwards. Splicing from direct I/O or DAX is handled by the caller.
