adi_v5_jtag: reduce verbosity on persistent WAIT

In case of AP not responding, e.g. not clocked, the first WAIT
reply is logged as:
	DAP transaction stalled (WAIT) - slowing down
then OpenOCD retries the transaction few times, until it timeouts.
At each retry it prints the message:
	DAP transaction stalled during replay (WAIT) - resending
Depending on JTAG speed and transport latency, the amount of log
messages can be quite annoying and not relevant.
The last printed line is at timeout:
	Timeout during WAIT recovery

Reduce the verbosity.
