task: add a function to check if a task is active

lyakh · lgirdwood · commit 9bd130db1cb7 · 2021-11-25T23:01:36.000Z
Tasks currently have 9 states defined for them, but they all can be
divided into two groups: active and passive. We define all tasks on a
scheduler queue as active. All other tasks are passive.
