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.
