[PATCH 28/48] qemu: Assume QEMU_CAPS_VIRTIO_NET_TX_QUEUE_SIZE

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Introduced in QEMU's commit of v2.10.0-rc0~95^2~20 the
.tx_queue_size attribute of virtio-net device is always available
for all QEMU versions we support (4.2.0, currently). Therefore,
we can assume the capability is always set and thus doesn't need
to be checked for.
