Subject: [PATCH] btrfs: also add stripe entries for NOCOW writes

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

NOCOW writes do not generate stripe_extent entries in the RAID stripe
tree, as the RAID stripe-tree feature initially was designed with a
zoned filesystem in mind and on a zoned filesystem, we do not allow NOCOW
writes. But the RAID stripe-tree feature is independent from the zoned
feature, so we must also allow NOCOW writes for zoned filesystems.
