(grnet) Move disk options before nic ones in kvm command

Older versions of Ganeti did ensure that during startup
disk devices will be inserted before nic devices in PCI

depending on the order of command line options....

KVM: set IFF_ONE_QUEUE on created tap interfaces

The IFF_ONE_QUEUE flag directs the kernel to only queue tap packets once

qdisc), possibly avoiding interface stalls when one of the queues overruns....

KVM: use running HVPs to calc blockdev options

2) Slot 1 will always be ISA bridge.
3) Slot 2 will always be VGA controller (even with -display none)....

Fix bitarray ops wrt PCI slots

Introduce new method `_GetFreeSlot()` responsible only for bitarray
operations. It fixes search in case of bitarray is either '0000..'
or '1111..'.

Use it instead of `_UpdatePCISlots()` and in `_GetFreePCISlot()`.
