afs: Fix copy_file_range()
The prevention of splice-write without explicit ops made the copy_file_write() syscall to an afs file (as done by the generic/112 xfstest) fail with EINVAL. Fix by using iter_file_splice_write() for afs. Fixes: 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
