msm: camera: icp: Remove bw vote of context in Release

Do not rely on timer expiry to remove bw of current context
if it is getting released. If context release is coming
before timer expiry (from last request submit), we are not
removing current context's vote from hw mgr and thus
from cpas. This will accumulate the bandwidth and causes
clocks to go to turbo and also into overflow issues if
the bw variables in cpas are wrapping around in long
hours testing.
