Subject: [PATCH] ALSA: usb-audio: remove is_playback from implicit feedback
 quirks

An implicit feedback endpoint can only be a capture source. The
consumer (sink) of the implicit feedback endpoint is therefore limited
to playback EPs.
Check if the target endpoint is a playback first and remove redundant
checks.
