ALSA: usb-audio: Check max frame size for implicit feedback mode, too
[ Upstream commit 7cb2a5422f5bbdf1cf32eae0eda41000485b9346 ]
When the packet sizes are taken from the capture stream in the
implicit feedback mode, the sizes might be larger than the upper
boundary defined by the descriptor. As already done for other
transfer modes, we have to cap the sizes accordingly at sending,
otherwise this would lead to an error in USB core at submission of
URBs.
