Subject: Btrfs: fix access_ok() check in btrfs_ioctl_send()

commit 700ff4f095d78af0998953e922e041d75254518b upstream.

The closing parenthesis is in the wrong place.  We want to check
"sizeof(*arg->clone_sources) * arg->clone_sources_count" instead of
"sizeof(*arg->clone_sources * arg->clone_sources_count)".
