kernfs: wire up ->splice_read and ->splice_write 



Wire up the splice_read and splice_write methods to the default
helpers using ->read_iter and ->write_iter now that those are
implemented for kernfs.  This restores support to use splice and
sendfile on kernfs files.

Fixes: 36e2c742 ("fs: don't allow splice read/write without explicit ops")
