Bluetooth: Set filter policy for LE connection

This patch sets the filter policy to a default value 0x01 during
LE auto connection if the destination address is not set. And it
updates the destination address once the LE connection complete
event is recieved during LE auto connection. And for it checks
valid destination address before cancelling LE connection when
connection timeout occurs.
