ALSA: usb-audio: Move txfr_quirk handling to quirk_flags
The txfr_quirk field was meant for aligning the transfer, and it's set for certain devices in quirks-table.h. Now we can move that stuff also to the new quirk_flags gracefully, and reduce the quirks-table.h entries (that are exposed to module device table). As the quirks-table.h entries are also with the name string override, provide the corresponding entries to the usb_audio_names[] table, too.
