Subject: [PATCH] ALSA: usb-audio: add quirk for RODE NT-USB+

The RODE NT-USB+ is marketed as a professional usb microphone, however the
usb audio interface is a mess:

[    1.130977] usb 1-5: new full-speed USB device number 2 using xhci_hcd
[    1.503906] usb 1-5: config 1 has an invalid interface number: 5 but max is 4
[    1.503912] usb 1-5: config 1 has no interface number 4
[    1.519689] usb 1-5: New USB device found, idVendor=19f7, idProduct=0035, bcdDevice= 1.09
[    1.519695] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[    1.519697] usb 1-5: Product: RØDE NT-USB+
[    1.519699] usb 1-5: Manufacturer: RØDE
[    1.519700] usb 1-5: SerialNumber: 1D773A1A
[    8.327495] usb 1-5: 1:1: cannot get freq at ep 0x82
[    8.344500] usb 1-5: 1:2: cannot get freq at ep 0x82
[    8.365499] usb 1-5: 2:1: cannot get freq at ep 0x2

Add QUIRK_FLAG_GET_SAMPLE_RATE to work around the broken sample rate get.
I have asked Rode support to fix it, but they show no interest.
