btrfs: zoned: don't skip block group profile checks on conventional zones

Browse Source 
On a zoned filesystem with conventional zones, we're skipping the block
group profile checks for the conventional zones.

This allows converting a zoned filesystem's data block groups to RAID when
all of the zones backing the chunk are on conventional zones.  But this
will lead to problems, once we're trying to allocate chunks backed by
sequential zones.

So also check for conventional zones when loading a block group's profile
on them.
