Hey Sasha,

this patch is just a readability cleanup, no reason to backport it.

Thanks, Johannes

 btrfs: zoned: exit btrfs_can_activate_zone if BTRFS_FS_NEED_ZONE_FINISH is set
 
 [ Upstream commit 26b38e28162ef4ceb1e0482299820fbbd7dbcd92 ]
 
 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.
