[PATCH 3/3] tools/vm/slabinfo: update struct slabinfo members' types

[Sergey Senozhatsky]

Align some of `struct slabinfo' members' types with
`struct kmem_cache' to suppress gcc warnings:

slabinfo.c:847:22: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:869:20: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:872:22: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:894:20: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
