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.
