wifi: ath10k: do not always wait for MSA_READY indicator

Browse source 
The ath10k driver waits for an "MSA_READY" indicator
to complete initialization. If the indicator is not
received, then the device remains unusable.

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.
