Revert the MFC of the r244237, done as r244806.  There are indeed bugs
in XEN pmap.  The revert hides a panic with the cost of non-working
vfork(2), which means more obscure misbehaviour in the usermode.
Revert is only done on the stable branch to maintain the consistent
erratic behaviour.

When the igb driver is static there are cases when early interrupts occur,
resulting in a panic in refresh_mbufs, to prevent this add a check to the
interrupt handler for DRV_RUNNING.
