[PATCH AUTOSEL 4.4 17/18] tools/vm/slabinfo.c: fix sign-compare warning

[ Upstream commit 904506562e0856f2535d876407d087c9459d345b ]

Currently we get the following compiler warning:

slabinfo.c:854:22: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
if (s->object_size < min_objsize)

due to the mismatch of signed/unsigned comparison. ->object_size and
->slab_size are never expected to be negative, so let's define them as
unsigned int.

[n-horiguchi@xxxxxxxxxxxxx: convert everything - none of these can be negative]
