xen/pciback: Don't disable PCI_COMMAND on PCI device reset.

I'm aware that this change is incompatible with qemu < 2.5, but that's now quite old.  Do you think it makes sense to apply this change to some stable branches?

Hey Ben,

<shrugs> My opinion is to drop it, but if Juergen thinks it makes sense to backport I am not going to argue.

I'm with Konrad here.
