qemu: Always reset @info in qemuDomainGetJobInfo

qemuDomainGetJobInfo didn't always reset the return data in @info.
Thankfully this wouldn't be a problem as the RPC layer does it but we
should do it anyways.

Since we reset the struct we don't have to set the type to
VIR_DOMAIN_JOB_NONE as the value is 0.
