CdmaSST: trigger getCDMASubscription after EVENT_RUIM_RECORDS_LOADED.

1. In CdmaLteSST, when EVENT_RUIM_RECORDS_LOADED, OTASP state
(MDN, MIN, SID, NID, PRL-Ver) will be loaded from RUIM card, and
ATEL won't trigger getCDMASubscription to get OTASP state from
network again. But actually user need OTASP state from network
instead of from card.

2. Move EVENT_RUIM_RECORDS_LOADED implementation from CdmaLteSST
to parent class CdmaSST. Because this situation is also suitable
for CdmaSST.

3. Remove LTE_ON_CDMA check in EVENT_RUIM_READY, and get rid of
getCDMASubscription, which will be done in EVENT_RUIM_RECORDS_LOADED.
