Fix setting of protection bits for page table entries in pmap_map(). This
function is only called from vm_page_startup() and vm_reserv_startup().
I.e. during vm subsystem initialization. As VM_PROT_WRITE is always
used in these calls, the typo did not have any effect. Likely, it's
the reason why it wasn't discovered so long.
