For the VM_PHYSSEG_DENSE case, checking the requested range to fall
into the area backed by vm_page_array wrongly compared end with
vm_page_array_size.  It should be adjusted by first_page index to be
correct.

Also, the corner and incorrect case of the requested range extending
after the end of the vm_page_array was incorrectly handled by
allocating the segment.

Fix the comparision for the end of range and return EINVAL if the end
extends beyond vm_page_array.
