Eliminate unnecessary uses of PHYS_TO_VM_PAGE() from pmap_enter(). These
uses predate the change in the pmap_enter() interface that replaced the
page's physical address by the address of its vm_page structure. The
PHYS_TO_VM_PAGE() was being used to compute the address of the same vm_page
structure that was being passed in.
