GAP: Use proper page scan rep mode for connection

Issue: Page time out seen when user initiated pairing from LE scan response

Steps to reproduce
==================
Steps:
1. Turn on BT
2. inquiry any dual mode device
3. Initiate pairing (only LE scan response received but br/edr
   inquiry response not received)

Actual Result:
Remote name request or create connection got page timeout some times

Expected result:
Remote name request and create connection should be successful

Root Cause:
If user finds only LE scan response for dual mode  devices, then stack
treats it as dual mode based on br/edr not supported bit. If pairing
initiated from LE scan response, then stack initiates RNR and ACL connection
on br/edr transport with wrong page scan response from LE inquiry database,
it leads to page time out.

Fix:
Use page scan response from inquiry data base if br/edr inquiry response
received, else use default page scan response R1 in RNR and create connection.

Test: Follow steps above
