mm: mm_init: use div64_ul() instead of do_div()
Fixes Coccinelle/coccicheck warning reported by do_div.cocci.
Compared to do_div(), div64_ul() does not implicitly cast the divisor and
does not unnecessarily calculate the remainder.
There are no functional changes. The benefit is purely a semantic cleanup
that better communicates the intent of the division and resolves the
static analysis warning.
