6.1-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit b2ccab3199aa7cea9154d80ea2585312c5f6eba0 ]
Pass a reference to the per-AG structure to xfs_free_extent. Most callers already have one, so we can eliminate unnecessary lookups. The one exception to this is the EFI code, which the next patch will fix.
