btrfs: don't try to delete RAID stripe-extents if we don't need to
Even if the RAID stripe-tree is not enabled in the filesystem, do_free_extent_accounting() still calls into btrfs_delete_raid_extent(). Check if the extent in question is on a block-group that has a profile which is used by RAID stripe-tree before attempting to delete a stripe extent. Return early if it doesn't, otherwise we're doing a unnecessary search.
