nr_to_scan needs to be (unsigned) long, not int, otherwise we get negative values on 32bit systems during shrink resulting in lots of messages like one below.

[ 4078.989603] shrink_slab: i915_gem_inactive_scan+0x0/0xc0 negative objects to delete nr=-289580136

Introduced in "drivers: convert shrinkers to new count/scan API" (383e4f4a4cdeb2dd552e90811089bcb4d41eb32e in linux-next.git)
