Pass kernend as the start parameter to uvm_page_physload(). This

Browse Source 
fixes pmap_steal_memory() as it can now unplug from the start of the
segment.  This might be the right thing to do too as the pages before
kernend are accessed via directly mapped P1, but i need to ask someone
with a clue.  This is also what evbsh3 always did.

Anyway, this at least unbreaks landisk after uvm hotplug fallout.
