init.qcom.rc: remove critical flag from dashd

* Somehow, some third-party stuff can mess up the context of dashd and
  prevent it from starting. We cannot fix third-party stuff, but at
  least it makes sense that dashd isn't that "critical" to the point
  that the whole system shuts down just because of this single service.
