xen: restore vcpu_info mapping
If we're using vcpu_info mapping, then make sure its restored on all
processors before relasing them from stop_machine.
The only complication is that if this fails, we can't continue because
we've already made assumptions that the mapping is available (baked in
calls to the _direct versions of the functions, for example).
Fortunately this can only happen with a 32-bit hypervisor, which may
possibly run out of mapping space. On a 64-bit hypervisor, this is a
non-issue.
