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")
