Subject: [PATCH 3/3] module: Remove superfluous call to klp_module_going()

Now that patched modules cannot suddenly disappear we could
theoretically remove klp_module_going() altogether. Unfortunately we
cannot do that in practice. Loading of a patched module may fail and we
need to execute right the actions implemented in klp_module_going().

Remove the call from delete_module syscall though, because that one is
really superfluous.
