kib 568d99bbad Properly handle possible underflow in vm_fault_prefault().
In vm_fault_prefault(), if backward count causes underflow in
calculation of
	starta = addra - backward * PAGE_SIZE;
then starta must be clipped to entry->start, instead of zero.
Clipping to zero allowed mapping outside of the map entries address
ranges, in particular, map at zero.
