[PATCH] hugetlb: fix error return for brk() entering a hugepage region 

Commit cb07c9a1864a8eac9f3123e428100d5b2a16e65a causes the wrong return
value.  is_hugepage_only_range() is a boolean, so we should return
-EINVAL rather than 1.

Also - we can use "mm" instead of looking up "current->mm" again.
