With LE/SMP the completion of a security level elavation from medium to

auth_complete and encryption_change, which is also where most of the

This patch changes way LE Connection Complete event with error status are
handled. BDADDR returned in such event packet do not need to be valid and
should not be used to search for existing hci_conn. Instead, any hci_conn
with BT_CONNECT state should be matched since there can be only one
pending LE outgoing connection at any time.
If not handled properly, appriopriate hci_conn will not be removed and
subsequent connection to given peer will try to reuse it without making
actual connection attempt.

It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).
It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

If controller is reset during the discovery procedure, Start Discovery
command stops working. This can be easily reproduced by running
"hciconfig hci0 reset" while discovering devices, for instance.
We should force discovery state to DISCOVERY_STOPPED in case we receive

active discovery states (DISCOVERY_INQUIRY, DISCOVERY_LE_SCAN and
DISCOVERY_RESOLVING) and subsequent Start Discovery commands will simply
