qcacmn: Fix the yield status for timer yield check

The dp_should_timer_irq_yield should return the
status DP_TIMER_NO_YIELD when no yield condition
has been met. Currently its returning the status
DP_TIMER_TIME_EXHAUST which causes the timer to yield
before the expected time.

Fix the return status from dp_should_timer_irq_yield
