[PATCH] uml: avoid already done dirtying

The PTE returned from handle_mm_fault is already marked as dirty and accessed
if needed.

Also, since this is not set with set_pte() (which sets NEWPAGE and NEWPROT as
needed), this wouldn't work anyway.

This version has been updated and fixed, thanks to some feedback from Jeff Dike.
