btrfs: zoned: return error from btrfs_zone_finish_endio()

Browse Source 
Now that btrfs_zone_finish_endio_workfn() is directly calling
do_zone_finish() the only caller of btrfs_zone_finish_endio() is
btrfs_finish_one_ordered().

btrfs_finish_one_ordered() already has error handling in-place so
btrfs_zone_finish_endio() can return an error if the block group lookup
fails.

Also as btrfs_zone_finish_endio() already checks for zoned filesystems and
returns early, there's no need to do this in the caller.
