Mmgrab was introduced in commit f1f1007644ff ("mm: add new mmgrab() helper") and most of the kernel was updated to use it. Update a remaining file.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
<smpl> @@ expression e; @@ - atomic_inc(&e->mm_count); + mmgrab(e); </smpl>
