Bluetooth: L2CAP: Fix not responding with L2CAP_CR_LE_ENCRYPTION

Browse source

[ Upstream commit 03dba9cea7 ]

Depending on the security set the response to L2CAP_LE_CONN_REQ shall be
just L2CAP_CR_LE_ENCRYPTION if only encryption when BT_SECURITY_MEDIUM
is selected since that means security mode 2 which doesn't require
authentication which is something that is covered in the qualification
test L2CAP/LE/CFC/BV-25-C.
