cfq: calculate the seek_mean per cfq_queue not per cfq_io_context
commit b2c18e1e08a5a9663094d57bb4be2f02226ee61c upstream.
async cfq_queue's are already shared between processes within the same
priority, and forthcoming patches will change the mapping of cic to sync
cfq_queue from 1:1 to 1:N. So, calculate the seekiness of a process
based on the cfq_queue instead of the cfq_io_context.
