Dongxiang Ke 6123bec848 ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface() 
commit e53f47f6c1a56d2af728909f1cb894da6b43d9bf upstream.

There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and
the number of it's interfaces less than 4, an out-of-bounds read bug occurs
when parsing the interface descriptor for this device.

Fix this by checking the number of interfaces.
