Subject: ALSA: usb-audio: don't try to get Outlaw RR2150 sample rate

From: Eric Wong <normalperson@yhbt.net>

commit 2f80b2958abe5658000d5ad9b45a36ecf879666e upstream.

This quirk allows us to avoid the noisy:

	current rate 0 is different from the runtime rate

message every time playback starts.  While USB DAC in the RR2150
supports reading the sample rate, it never returns a sample rate
other than zero in my observation with common sample rates.
