If gsm driver fails to activate one mux, and this mux is not stored in
gsm_mux[], there would be a warning in gsm_cleanup_mux(). Actually this
is a legal case. So just do a simple check instead of WARN_ON.

There is one filed gsm->num to store its index of gsm_mux[]. So use
gsm->num to remove itself from gsm_mux[] instead of the for-loop
traverse.
