Bluetooth: Reset the security timer when a command is queued
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 Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@openbossa.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
