trace/hwlat: Switch disable_migrate to mode none
When in the round-robin mode, if the tracer detects a change in the
hwlatd thread affinity by an external tool, e.g., taskset, the
round-robin logic is disabled. The disable_migrate variable currently
tracks this.
With the addition of the "mode" config and the mode "none," the
disable_migrate logic is equivalent to switch to the "none" mode.
Hence, instead of using a hidden variable to track this behavior,
switch the mode to none, informing the user about this change.
