Log Message:
pmap_tlb_shootdown_all_user() can be called in the PV scenario as well
as the forward scenario, for example if a pmap_page_protect() to remove
all mappings results in the freeing of a PT page. It therefore needs
to do the same reference counting dance as pmap_tlb_shootdown_pv().
Also fix a use-after-free error in pmap_page_protect().
Add / tweak some assertions, and shrink the pmap::pm_count field from
long to unsigned int (which gave me a spare unsigned int field for
debugging purposes).
