[PATCH 2/2] wifi: ath10k: work around missing MSA_READY indicator

[Marc Gonzalez <mgonzalez@freebox.fr>]

From: Pierre-Hugues Husson <phhusson@freebox.fr>

On our APQ8998 device, driver never receives MSA_READY indicator.
We only seem to receive FW_READY and PIN_CONNECT indicators.
Not waiting for the MSA_READY indicator seems to fix the WiFi.
