[PATCH] msync: fix return value

msync() does a strange thing.  Essentially:

vma = find_vma();
for ( ; ; ) {
if (!vma)
return -ENOMEM;
...
vma = vma->vm_next;
}

so an msync() request which starts within or before a valid VMA and which ends
within or beyond the final VMA will incorrectly return -ENOMEM.

Fix.
