[PATCH v2 3/4] btrfs: zoned: sink zone check into btrfs_repair_one_zone

From: Johannes Thumshirn <hidden>
Date: 2021-12-07 14:29:31
Subsystem: btrfs file system, filesystems (vfs and infrastructure), the rest · Maintainers: Chris Mason, David Sterba, Alexander Viro, Christian Brauner, Linus Torvalds

Sink zone check into btrfs_repair_one_zone() so we don't need to do it in
all callers.

Also as btrfs_repair_one_zone() doesn't return a sensible error, make it a
boolean function and return false in case it got called on a non-zoned
filesystem and true on a zoned filesystem.
