doc/sequence_charts: fix naming of mncc_fsm to mncc_call
mncc_fsm.[hc] were renamed to mncc_call.[hc] during patch review, which failed to carry through to this sequence chart. Also fix the MNCC_ST_* to MNCC_CALL_ST_* and MNCC_EV_* to MNCC_CALL_EV_*. Change-Id: I03ee1b43ab95dca3c43fdb9e92dc158aad5a4203
