include/linux/mm.h: provide consistent declaration for num_poisoned_pages

clang reports the following compile warning.

  In file included from mm/vmscan.c:56:
  ./include/linux/swapops.h:327:22: warning:
	section attribute is specified on redeclared variable [-Wsection]
  extern atomic_long_t num_poisoned_pages __read_mostly;
  ./include/linux/mm.h:2585:22: note: previous declaration is here
  extern atomic_long_t num_poisoned_pages;

Let's use __read_mostly everywhere.
