btrfs: remove the cross file system checks from remap
The sb check is already done in do_clone_file_range, and the mnt check
(which will hopefully go away in a subsequent patch) is done in
ioctl_file_clone(). Remove the check in our code and put an ASSERT() to
make sure it doesn't change underneath us.
