Fix cdma data call failure due to incorrect RuimRecords loaded state.

Don't reset mRecordsRequested after records loaded as it causes
getRecordsLoaded() to return false always.
Remove check for mRecordsRequested in fetchRuimRecords() to fix
SIM REFRESH issue and make sure recordsRequired() calls
fetchRuimRecords() only once.
