Btrfs: remove BUG() in print_extent_item
btrfs_print_leaf() is used in btrfs_get_extent_inline_ref_type, so here we really want to print the invalid value of ref type instead of causing a kernel panic. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
