SW steering uses RC QP to write/read to/from ICM, hence it's not supported when RoCE is not supported as well.

* Qgroup equivalent for @size @reserved

* about things like csum size nor how many tree blocks it will need to
* reserve.
*
* Qgroup cares more about net change of the extent usage.
*
* So for one newly inserted file extent, in worst case it will cause
* leaf split and level increase, nodesize for each file extent is
* already too much.
*
* In short, qgroup_size/reserved is the upper limit of possible needed
* qgroup metadata reservation.
