Btrfs-progs: don't assert when we have an invalid mapping
Asserting is no fun, we may be able to recover from this error in certain cases (like btrfs-image and btrfsck). Just do what the kernel does and spit out an error and return that there is only 1 copy. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: David Sterba <dsterba@suse.cz>
