The config_bus_number is an offset within the config space reserved for
the devices behind the VMD, while bus_number refers to the actual bus
number assigned by VMD that depend on the VMCAP and VMCONFIG registers.
So, to access the mapped config space we have to use config_bus_number.
We didn't do that when resetting root ports', which could lead to
segfaults if these values were different, as we'd access unmapped
memory.
Fixes#2451
