[PATCH] btrfs: zoned: exit btrfs_can_activate_zone if BTRFS_FS_NEED_ZONE_FINISH is set

[Johannes Thumshirn <jth@kernel.org>]

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

If BTRFS_FS_NEED_ZONE_FINISH is already set for the whole filesystem, exit
early in btrfs_can_activate_zone(). There's no need to check if
BTRFS_FS_NEED_ZONE_FINISH needs to be set if it is already set.
