ovl: simplify file splice
generic_file_splice_read() and iter_file_splice_write() will call back into
f_op->iter_read() and f_op->iter_write() respectively. These already do
the real file lookup and cred override. So the code in ovl_splice_read()
and ovl_splice_write() is redundant.
In addition the ovl_file_accessed() call in ovl_splice_write() is
incorrect, though probably harmless.
Fix by calling generic_file_splice_read() and iter_file_splice_write()
directly.
