Simplify and clarify the implementation of the pmap_page_protect(9) API.
This function is only ever called with PROT_NONE or PROT_READ where
PROT_NONE removes the mapping from the page tables and PROT_READ takes
away write permission.  Add a KASSERT to make sure no other values are
passed.  This KASSERT should be optimized away by any decent compiler.
