[S390] cmm: fix crash on module unload

There might be a scheduled cmm_timer if the cmm module gets unloaded.
That timer was not deleted during module unload and thus could lead
to system crash later on.
Besides that reorder function calls in module init and exit code to
avoid a couple of other races which could lead to accesses to
uninitialized data.
