GAP: Dont send RNR and create connection at the same time

HOST sending create connection, Remote Name Request (RNR) back to back
for same remote due to incorrect conditional logic.
Hence soc not able to respond for create connection,
DUT stuck in pairing state for ever.

Test: RNR is not sent when create connection is in progress
