block: doc: add slice_idle_us to bfq documentation
Of the tunables available for the bfq I/O scheduler, the only one missing from the documentation in 'Documentation/block/bfq-iosched.txt' is slice_idle_us. Add this tunable to the documentation and a short explanation of its purpose. Acked-by:Paolo Valente <paolo.valente@linaro.org> Signed-off-by:
