qemu: move virDomainLiveConfigHelperMethod right after BeginJob
qemu: move virDomainLiveConfigHelperMethod right after BeginJob

We should call virDomainLiveConfigHelperMethod ASAP because this
function transfers VIR_DOMAIN_AFFECT_CURRENT to VIR_DOMAIN_AFFECT_LIVE
or VIR_DOMAIN_AFFECT_CONFIG.  All other additional checks for those two
flags should consider that the user give us VIR_DOMAIN_AFFECT_CURRENT.

Remove the unnecessary check whether the domain is live in case of
VIR_DOMAIN_VCPU_GUEST because this check is done by
virDomainLiveConfigHelperMethod.
