[PATCH AUTOSEL 6.1 040/212] btrfs: zoned: exit btrfs_can_activate_zone if BTRFS_FS_NEED_ZONE_FINISH is set

[Sasha Levin <sashal@kernel.org>]

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

[ 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.
