xua_aspm_fsm: Remove unneeded workaround submitting XUA_ASP_E_M_ASP_ACTIVE_REQ

Sending that kind of event is up to the layer manager.
Right now, all ASPs (except ipa_aspm_fsm, which don't need that event
because there's no ACTIVATE in IPA) have an associated layer manager
FSM, so that workaround is not needed.
