cfq-iosched: move group scheduling functions under ifdef
If CFQ_GROUP_IOSCHED is not set, the 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)
^
In reality, two other lookup functions aren't used either if
CFQ_GROUP_IOSCHED isn't set. Move all three under one of the
CFQ_GROUP_IOSCHED sections in the code.
