wcn36xx: Wait longer for SMD commands to complete
On some wcnss firmwares the start command can take up to 300ms to
complete. Currently there is a 200ms timeout for SMD command to
complete which causes the start to fail.
Increase the timeout to 500ms. Also improve debug information
regarding SMD command completion time.
