Konstantin Belousov fcd0c06eee Correct some inconsistencies in the earliest created kernel page 
tables which affect demotion.

The last last-level page table under 2M mappings below KERNend was
only partially initialized.  When that page was used as the hardware
page table for demotion of the 2M mapping, the result was not
consistent.  Since pmap_demote_pde() is switched to use PG_PROMOTED as
the test for the validity of the saved last level page table page, we
can keep page table pages zero-initialized instead.  Demotion would
fill them as needed.

Only map the created page tables beyond KERNend, there is no need to
pre-promote PTmap after KERNend, because the extra mapping is not used.

Only round up *firstaddr to 2M boundary when it is below rounded
KERNend.  Sometimes the allocpages() calls advance *firstaddr past the
end of the last 2MB page mapping. In that case, this conditional
avoids wasting an average of 1MB of physical memory.

Update comments to explain action in more clean and direct language.
