Anshuman Khandual 5093c5872b mm/vma: append unlikely() while testing VMA access permissions ...

It is unlikely that an inaccessible VMA without required permission flags
will get a page fault.  Hence lets just append unlikely() directive to
such checks in order to improve performance while also standardizing it
across various platforms.
