In certain scenarios, the semaphore sem_ticker_api_cb may be taken
during attempt to complete a synchronous ticker operation such as start

happen if ticker temporarily runs out of ticker operation slots for any
ticker client.
The consequence of ULL stuck waiting in semaphore is anything from
allocation assertions to watchdog timeouts.
This commit also sets a timeout on ull_disable calls, which relies on
the disable callback being invoked from 'done'. Invocation of 'done' is
mandatory, and code shall not allow that not to happen, but to avoid
hiding the real cause, the semaphore now has a timeout which causes
