Takashi Iwai efb75df105 ALSA: usb-audio: Skip generic sync EP parse for secondary EP 
When ep_idx is already non-zero, it means usually a capture stream
that is set up explicity by a fixed-format quirk, and applying the
check for generic (non-implicit-fb) sync EPs might hit incorrectly,
resulting in a bogus sync endpoint for the capture stream.

This patch adds a check for the ep_idx and skip if it's a secondary
endpoint.  It's a part of the fixes for regressions on Saffire 6.

Fixes: 7b0efea4ba ("ALSA: usb-audio: Add missing ep_idx in fixed EP quirks")
