netprio_cgroup: convert away from cftype->read_map()
In preparation of conversion to kernfs, cgroup file handling is being
consolidated so that it can be easily mapped to the seq_file based
interface of kernfs.
cftype->read_map() doesn't add any value and being replaced with
->read_seq_string(). Update read_priomap() to use ->read_seq_string()
instead.
This patch doesn't make any visible behavior changes.
