Deal with unknown signal strength level comes from Telephony 

According to TS27.007 8.5, GSM level 99 represents
not known or not detectable. Bluetooth doesn't take it into
consideration, so HF unit cannot display correct signal level.

Add judgement for this special case so that HF unit can match
with status bar of phone.
