cfq-iosched: Always provide group isolation.
Effectively, make group_isolation=1 the default and remove the tunable.
The setting group_isolation=0 was because by default we idle on
sync-noidle tree and on fast devices, this can be very harmful for
throughput.
However, this problem can also be addressed by tuning slice_idle and
possibly group_idle on faster storage devices.
This change simplifies the CFQ code by removing the feature entirely.
