[PATCH] proc: fix missing reference of mm

From: Sudip Mukherjee
Date: Wed Jan 20 2016 - 23:55:42 EST

The defconfig build of blackfin was failing with the error:
fs/proc/task_nommu.c: In function 'is_stack':
fs/proc/task_nommu.c:132:28: error: 'mm' undeclared (first use in this function)

While reverting /proc/<pid>/maps [stack:TID] annotation a reference to
mm was missed.

Fixes: e87d4fd02f40 ("proc: revert /proc/<pid>/maps [stack:TID] annotation")
