HFP: check pending retry connect devices while attempt new connection
In some corner case, while first HS is connected, and hfp retry connection
for second HS is pending in delayed message, then outgoing or incoming hfp
connection from third HS, as a result, HFP get connected for all 3 HS finally.
1) HFP get connected with 1st HS.
2) Pending 2500ms for HFP retry connection with 2nd HS.
3) In less than 2500ms, incoming HFP connection from the 3rd HS, HFP get
connected with 3rd HS.
4) 2500ms later after step2, retry connect with 2nd HS and HFP get connected
successfully with 2nd HS.
Check pending retry connect devices while attempt new connection to avoid this
corner case.
