Due to RadioTuner API documentation, onTuneFailed should be called
when a pending tuning operation is canceled. Therefore, a new
result value Canceled was added in broadcast radio HAL. The
onTuneFailed callback for pending tuning operations in default HAL
was implemented by adding whatIfCanceled function field in Task
struct in WorkerThread utils class.

Currently mThread is started in initializer list, but
not in constructor, when the thread starts in initializer
list, not all class members are init yet (depends on the
order of class member declarations).
And mThread will use class members.
Putting mThread to starts in constructor ensures all
class member variables are init before thread starts.
