Bluetooth: use the proper scan params when conn is pending
When an LE connection is requested and an RPA update is needed via
hci_connect_le_scan, the default scanning parameters are used rather
than the connect parameters. This leads to significant delays in the
connection establishment process when using lower duty cycle scanning
parameters.
The patch simply looks at the pended connection list when trying to
determine which scanning parameters should be used.
