xfs: move xfs_extent_free_defer_add to xfs_extfree_item.c

Source kernel commit: 84a3c1576c5aade32170fae6c61d51bd2d16010f

Move the code that adds the incore xfs_extent_free_item deferred work
data to a transaction to live with the EFI log item code.  This means
that the allocator code no longer has to know about the inner workings
of the EFI log items.

As a consequence, we can get rid of the _{get,put}_group helpers.
