[libvirt PATCH] qemu_firmware: don't error out for unknown firmware features

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

When QEMU introduces new firmware features libvirt will fail until we
list that feature in our code as well which doesn't sound right.

We should simply ignore the new feature until we add a proper support
for it.
