Systematically removing the LE connection parameters and autoconnect
action is inconvenient for rebonding without disconnecting from
userland (i.e. unpairing followed by repairing without
disconnecting). The parameters will be lost after unparing and
userland needs to take care of book-keeping them and re-adding them.
This patch allows userland to forget about parameter management when
rebonding without disconnecting. It defers clearing the connection
parameters when unparing without disconnecting, giving a chance of
keeping the parameters if a repairing happens before the connection is
closed.

There are scenarios when autoconnecting to a device after the
reception of an ADV_IND report (action 0x02), in which userland
might want to examine the report's contents.
For instance, the Service Data might have changed and it would be
useful to know ahead of time before starting any GATT procedures.
Also, the ADV_IND may contain Manufacturer Specific data which would
be lost if not propagated to userland. In fact, this patch results
from the need to rebond with a device lacking persistent storage which
notifies about losing its LTK in ADV_IND reports.
This patch appends the ADV_IND report which triggered the
autoconnection to the EIR Data in the Device Connected event.
