There is no need to check for this because all block drivers that have
children implement bdrv_child_perm and all callers already ensure that
bs->drv is set.
Furthermore, if this check would fail then the callers would end up
with uninitialized values for nperm and nshared.
This patch replaces the check with an assertion.
