Subject: virt: vbox: Log an error when we fail to get the host version
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=19972dd568f8d1e701f8051fcff56562e0551f63;p=openwrt%2Fstaging%2Fblogic.git

virt: vbox: Log an error when we fail to get the host version

This was the only error path during probe without a message being logged
about what went wrong, this fixes this.
