Currently ADM state change request that tries to set the
administrative state to the current value are immediately ACK'ed.
Beside the caching problem, this could lead the protocol
inconsistencies if two such requests are sent one after the other and
the second arrives before the procedure of the first has finished.

This patch removes the shortcut in oml_rx_chg_adm_state() which
immediately called oml_mo_statechg_ack(mo).
