Naohiro Aota b528f46713 btrfs: zoned: deal with holes writing out tree-log pages 
Since the zoned filesystem requires sequential write out of metadata, we
cannot proceed with a hole in tree-log pages. When such a hole exists,
btree_write_cache_pages() will return -EAGAIN. This happens when someone,
e.g., a concurrent transaction commit, writes a dirty extent in this
tree-log commit.

If we are not going to wait for the extents, we can hope the concurrent
writing fills the hole for us. So, we can ignore the error in this case and
hope the next write will succeed.

If we want to wait for them and got the error, we cannot wait for them
because it will cause a deadlock. So, let's bail out to a full commit in
this case.
