commit 8dbfc14fc736eb701089aff09645c3d4ad3decb1 upstream.
When using the block group tree feature, this tree is a critical tree just like the extent, csum and free space trees, and just like them it uses the delayed refs block reserve.
So take into account the block group tree, and its current size, when calculating the size for the global reserve.
