Log Message:
Pull up following revision(s) (requested by ozaki-r in ticket #1102):
sys/dev/pci/if_vioif.c: revision 1.5
Don't set SOFTINT_MPSAFE to vioif_rx_softint
vioif_rx_softint calls vioif_populate_rx_mbufs that is not MPSAFE.
vioif_populate_rx_mbufs is also called via vioif_ioctl and so can
be called by two LWPs simultaneously, resulting in kernel panic.
