[PATCH 31/48] qemu: Assume QEMU_CAPS_VIRTIO_NET_HOST_MTU

[Michal Privoznik]

Introduced in QEMU's commit of v2.9.0-rc0~162^2~10 the .host_mtu
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.
