soc: qcom: hab: run the dispatcher's tasklet w/ high priority 



HAB uses tasklets as the bottom half to receive message from the
remote side. Even when the whole system is overloaded, HAB clients
(e.g., audio, display, gfx) still expect low latency for good user
experience. So here, tasklet_hi_schedule() is used.
