If CFQ_GROUP_IOSCHED kernel option is not set, a compiler produces the
following warning:
CC block/cfq-iosched.o
linux/block/cfq-iosched.c:469:2:
warning: 'cpd_to_cfqgd' defined but not used [-Wunused-function]
*cpd_to_cfqgd(struct blkcg_policy_data *cpd)
^
Define this function only if CFQ_GROUP_IOSCHED is set and remove
the compilation warning.
