Bluetooth: Reset the security timer when a command is queued

Browse Source 
Each time a SMP command is enqueued, we reset the SMP timer,
this way we follow exactly what the spec mandates:

"The Security Manager Timer shall be reset when an L2CAP SMP command is
queued for transmission." Vol. 3, Part H, Section 3.4
