The ath10k driver waits for an "MSA_READY" indicator

received, then the device remains unusable.
cf. ath10k_qmi_driver_event_work()
Several msm8998-based devices are affected by this issue.
Oddly, it seems safe to NOT wait for the indicator, and
proceed immediately when QMI_EVENT_SERVER_ARRIVE.

The feedback I received was "it might be ok to change all ath10k qmi
to skip waiting for msa_ready", and it was pointed out that ath11k
(and ath12k) do not wait for it.
However with so many deployed devices, "might be ok" isn't a strong
argument for changing the default behavior.
