mm, mempolicy: silence gcc warning
Fengguang Wu reports that compiling mm/mempolicy.c results in a warning:
mm/mempolicy.c: In function 'mpol_to_str':
mm/mempolicy.c:2878:2: error: format not a string literal and no format arguments
Kees says this is because he is using -Wformat-security.
Silence the warning.
