kernel-wide: fix spelling mistakes like "assocative" -> "associative"

kernel-wide: fix spelling mistakes like "assocative" -> "associative"

There were several instances of the string "assocat" in the kernel, which
should have been spelled "associat", with the various endings of -ive,
-ed, -ion, and sometimes beginnging with dis-.

Add to the spelling dictionary the corrections so that future instances
will be caught by checkpatch, and fix the instances found.

Originally noticed by accident with a 'git grep socat'.
