ACS: Fix ACS behavior for channel selection

Browse source 
The current ACS algorithm incorrectly returns success even when there is
no survey list, leading to improper interference factor calculation.
This leads to treating 0 as a valid interference factor, which affects
channel selection judgment.

Fix the issue by ensuring success is only returned when the survey list
is not empty, thereby ignoring non-zero values in the interference
factor calculation.
