btrfs: make extent_write_locked_range() handle subpage writeback correctly
When extent_write_locked_range() generated an inline extent, it would
set and finish the writeback for the whole page.
Although currently it's safe since subpage disables inline creation,
for the sake of consistency, let it go with subpage helpers to set and
clear the writeback flags.
