x86/mm: Clean up types in xlate_dev_mem_ptr() some more

So Linus noticed that in:

  94d4b4765b7d ("x86/mm: Clean up types in xlate_dev_mem_ptr()")

... I added two nonsensical casts, due to the poor type choice
for 'vaddr'.

Change it to 'void *' and take advantage of void * arithmetics.

This removes the casts.

( Also remove a nonsensical return line from unxlate_dev_mem_ptr()
  while at it. )
