wifi: ath10k: avoid unnecessary wait for service ready message

[ Upstream commit 51a73f1b2e56b0324b4a3bb8cebc4221b5be4c7a ]

Commit e57b7d62a1b2 ("wifi: ath10k: poll service ready message before
failing") works around the failure in waiting for the service ready
message by active polling. Note the polling is triggered after initial
wait timeout, which means that the wait-till-timeout can not be avoided
even the message is ready.

A possible fix is to do polling once before wait as well, however this
can not handle the race that the message arrives right after polling.
So the solution is to do periodic polling until timeout.
