splice: remove permission hook from iter_file_splice_write()
All the callers of ->splice_write(), (e.g. do_splice_direct() and
do_splice()) already check rw_verify_area() for the entire range
and perform all the other checks that are in vfs_write_iter().
Instead of creating another tiny helper for special caller, just
open-code it.
This is needed for fanotify "pre content" events.
