btrfs: embed extent_changeset::range_changed to the structure
We can embed range_changed to the extent changeset to address following
problems:
- no need to allocate ulist dynamically, we also get rid of the GFP_NOFS
for free
- fix lack of allocation failure checking in btrfs_qgroup_reserve_data
The stack consuption where extent_changeset is used slightly increases:
before: 16
after: 16 - 8 (for pointer) + 32 (sizeof ulist) = 40
Which is bearable.
