btrfs: qgroup: Return actually freed bytes for qgroup release or free data
btrfs_qgroup_release/free_data() only returns 0 or a negative error number (ENOMEM is the only possible error). This is normally good enough, but sometimes we need the exact byte count it freed/released. Change it to return actually released/freed bytenr number instead of 0 for success. And slightly modify related extent_changeset structure, since in btrfs one no-hole data extent won't be larger than 128M, so "unsigned int" is large enough for the use case.
