Yonghua Huang 3391bffb27 hv:fix rtvm hang with maxcpus=0/1 in bootargs ...

RTVM (with lapic PT) boots hang when maxcpus is
 assigned a value less than the CPU number configured
 in hypervisor.

 In this case, vlapic_state(per VM) is left in TRANSITION
 state after BSP boot, which blocks interupts to be injected
 to this UOS.
