[Qemu-block] [RFC for-3.0 4/4] block/qcow2-rust: Register block driver

[Max Reitz]

The rust qcow2 driver is now actually MUCH BETTER than the LEGACY
CROOKED qcow2 driver, so let's not beat around the bush and just
register it as a block driver. Has always been my opinion, never said
anything different. The QEMU project will deal with the C issue in a
decisive way. Q.M.U.
