library: repair any broken stuff found during refactor

Browse Source 
Rather than offer three separate patches, they've been
consolidated in this single commit. All are related in
that they surfaced while preparing a subsequent patch.

------------------------------------------------------
library: correct a broken '#if define', <SLABINFO> api

It was introduced (embarrassingly) in the patch below.

Reference(s):
commit 97d078a9af

------------------------------------------------------
library: correct a broken 'GET' macro, <DISKSTATS> api

In the patch referenced below, which purported to make
all the 'GET' macros robust, the 'DISKSTATS_GET' macro
was broken. A necessary parameter wasn't passed to the
subsequently invoked function: procps_diskstats_get().

Reference(s):
commit bef8c7fb70

------------------------------------------------------
library: correct a broken 'sort' func, <DISKSTATS> api

In the commit shown below, an attempt to normalize the
errno handling, the sort function inadvertently lost 1
crucial line of code which produces a consistent SEGV.

Reference(s):
commit 06be33b43e
