Filipe Manana c28b97f53b btrfs: qgroups: remove bytenr field from struct btrfs_qgroup_extent_record
Now that we track qgroup extent records in a xarray we don't need to have
a "bytenr" field in  struct btrfs_qgroup_extent_record, since we can get
it from the index of the record in the xarray.

So remove the field and grab the bytenr from either the index key or any
other place where it's available (delayed refs). This reduces the size of
struct btrfs_qgroup_extent_record from 40 bytes down to 32 bytes, meaning
that we now can store 128 instances of this structure instead of 102 per
4K page.
