ALSA: usb-audio: Add quirk entries for NexiGo N930W webcam

The NexiGo N930W 60fps webcam (USB ID 3443:930d) hits the same
'cannot get freq at ep 0x84' error in snd-usb-audio as its sibling
N930AF (1bcf:2283). Without QUIRK_FLAG_GET_SAMPLE_RATE the ADC clock
is never configured and the microphone streams only zero samples.

Testing on Linux 6.17 with QUIRK_FLAG_GET_SAMPLE_RATE |
QUIRK_FLAG_MIC_RES_16 (via quirk_alias=3443930d:1bcf2283) confirmed
the microphone captures real audio after a cold USB re-enumeration.
Adding a native quirk_flags_table entry avoids the alias workaround.
