cfq-iosched: remove unused 'group_changed' in cfq_service_tree_add()
The 'group_changed' variable is initialized to 0 and never changed, so checking the variable is meaningless. It is a leftover from 0bbfeb832042 ("cfq-iosched: Always provide group iosolation."). Let's get rid of it. Signed-off-by: Namhyung Kim <namhyung@gmail.com> Cc: Justin TerAvest <teravest@google.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
