btrfs: handle invalid range and start in merge_extent_mapping()

Turn a BUG_ON to a properly handled error and update the error message
in the caller.  It is expected that @em_in and @start passed to
btrfs_add_extent_mapping() overlap. Besides tests, the only caller
btrfs_get_extent() makes sure this is true.
