btrfs: don't treat zoned writeback as being from an async helper thread

Browse source

When extent_write_locked_range was originally added, it was only used
writing back compressed pages from an async helper thread.  But it is
now also used for writing back pages on zoned devices, where it is
called directly from the ->writepage context.  In this case we want to
be able to pass on the writeback_control instead of creating a new one,
and more importantly want to use all the normal cgroup interaction
instead of potentially deferring writeback to another helper.
