msm: vidc: check operating rate before bus voting 



While voting bus bandwidth, considering instance fps for both
normal and high frame rate recording causing low bus arbitrary
bandwidth voting.

Operating rate is not considered for bus voting leading to insufficient
bandwidth errors in video usecases. This change fixes the issue by
considering operating rate for bus voting.
