ALSA: usb-audio: don't try to get Outlaw RR2150 sample rate
[ Upstream commit 2f80b2958abe5658000d5ad9b45a36ecf879666e ]
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.
