[libvirt] [PATCH] conf: Move virDomainPCIAddressBusIsFullyReserved()

[Andrea Bolognani]

This function was private to the QEMU driver and was,
accordingly, called qemuDomainPCIBusFullyReserved().

However, since it's really not QEMU-specific at all,
it makes a lot of sense to have it closer to the
virDomainPCIAddressBus struct it operates on; even more
so considering we're going to introduce a complementary
virDomainPCIAddressBusIsEmpty() function later on.
