blkcg: kill blkio_policy_node
Now that blkcg configuration lives in blkg's, blkio_policy_node is no
longer necessary. Kill it.
blkio_policy_parse_and_set() now fails if invoked for missing device
and functions to print out configurations are updated to print from
blkg's.
cftype_blkg_same_policy() is dropped along with other policy functions
for consistency. Its one line is open coded in the only user -
blkio_read_blkg_stats().
-v2: Update to reflect the retry-on-bypass logic change of the
previous patch.
