Bluetooth: Never deallocate a session when some DLC points to it

Fix a bug introduced in commit 9cf5b0ea3a7f1432c61029f7aaf4b8b338628884:
function rfcomm_recv_ua calls rfcomm_session_put without checking that
the session is not referenced by some DLC. If the session is freed, that
DLC would refer to deallocated memory, causing an oops later, as shown
in this bug report: https://bugzilla.kernel.org/show_bug.cgi?id=15994
