Theodore Ts'o 1f5a81e41f ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only files ...

Dan Roseberg has reported a problem with the MOVE_EXT ioctl.  If the
donor file is an append-only file, we should not allow the operation
to proceed, lest we end up overwriting the contents of an append-only
file.
