Eliminate the special case handling of OBJT_DEVICE objects in
vm_fault_additional_pages() that was introduced in revision 1.47. Then
as now, it is unnecessary because dev_pager_haspage() returns zero for
both the number of pages to read ahead and read behind, producing the
same exact behavior by vm_fault_additional_pages() as the special case
handling.
