xen: fix booting ballooned down hvm guest
Commit 96edd61dcf44362d3ef0bed1a5361e0ac7886a63 ("xen/balloon: don't online new memory initially") introduced a regression when booting a HVM domain with memory less than mem-max: instead of ballooning down immediately the system would try to use the memory up to mem-max resulting in Xen crashing the domain. For HVM domains the current size will be reflected in Xenstore node memory/static-max instead of memory/target. Additionally we have to trigger the ballooning process at once.
