CRAS: Format rate_estimator

Reformat codes with the .clang-format we just introduced.
To format whole files provided in-place:
clang-format -i -style=file [<file> ...]

BUG=chromium:950858
TEST=Add directory to check_format_error and run
FEATURES="test" USE=asan emerge-${BOARD} -v media-sound/adhd
