[Why]
The sequence is slightly changed when bring .set_bandwidth out
from the end of programming backend to the end of programming
surface. Vega10 doesn't like to get clocks updated if
stream_count is zero in the current context (Atomic Reset).
[How]
Do not update clocks if no stream is showing up in the context.
