Subject: [PATCH BlueZ v2 3/4] bap: Improve handling of pa_req timer

The patch handles timers on a per adapter basis.

The timer is now also started on setup_accept_io_broadcast, so
BAP_PA_BIG_SYNC_REQ can be treated if the timer is stopped in the meantime.
The timer is stopped if the bap_adapter's pa_req queue is empty.
A pa_timer_id equal to 0 means that the timer is stopped.
