mm/oom_kill: remove unnecessary integer promotion in format string

mm/oom_kill: remove unnecessary integer promotion in format string

The 'h' length modifier in '%hd' is unnecessary as short integers are
promoted to int in variadic functions.  Use '%d' instead.

Checkpatch flags the 'h' modifier as unnecessary for this reason, and
many other subsystems have moved to using %d for promoted types.
Hence, I think this patch aligns with kernel coding practices.
