ASoC: SDCA: Correct FDL locking in sdca_fdl_process()
The current locking in sdca_fdl_process() locks over
sdca_ump_cancel_timeout() and the timeout work function takes the same
lock, this can lead to a deadlock if the work runs as part of the
cancel. To fix this use scoped_guard and move the cancel timeout to be
outside the lock.
