The congestion_count was introduced into the struct cgroup by
commit d09d8df3 ("blkcg: add generic throttling mechanism"),
but since it is closely related to the blkio subsys, it is not
appropriate to put it in the struct cgroup, so let's move it to
struct blkcg. There should be no functional changes because blkcg
is per cgroup.
