Qu Wenruo 0591f04036 btrfs: prevent remounting to v1 space cache for subpage mount 
Upstream commit 9f73f1aef98b ("btrfs: force v2 space cache usage for
subpage mount") forces subpage mount to use v2 cache, to avoid
deprecated v1 cache which doesn't support subpage properly.

But there is a loophole that user can still remount to v1 cache.

The existing check will only give users a warning, but does not really
prevent to do the remount.

Although remounting to v1 will not cause any problems since the v1 cache
will always be marked invalid when mounted with a different page size,
it's still better to prevent v1 cache at all for subpage mounts.

Fixes: 9f73f1aef98b ("btrfs: force v2 space cache usage for subpage mount")
