Subject: mm: use kcalloc() instead of kzalloc() to allocate array

The advantage of kcalloc is, that will prevent integer overflows which
could result from the multiplication of number of elements and size and
it is also a bit nicer to read.

The semantic patch that makes this change is available in
https://lkml.org/lkml/2011/11/25/107
