In order to establish a LE connection we need the address type
information. User-space already pass this information to kernel

As most LE devices leave advertising mode when they enter the connected
state, we may want to "pass" that connection to other users.
The first user will be the pairing procedure, the connection is
established without an associated socket, after the pairing is
complete, userspace may want to discover via GATT what services the
newly bonded device has.
If userspace establishes the connection while the timeout still
hasn't expired, the connection will be re-used.

The cid or psm and the source address might not be enough to uniquely
identify a global channel, especially when the source address is our
own.
For instance, when trying to communicate with two LE devices in master
mode, data received from the both devices is sent to the same socket.
Fix this by taking the destination address into account when choosing
the socket.

Also upper layer might clear local busy condition before ack timer
expires saving few cycles for sending RNR.
This also prevents sending two RNRs in some cases where sending one

acking up to N I-frame).
