ALSA: usb-audio: Fix missing error check at mixer resolution test A check of the return value from get_cur_mix_raw() is missing at the resolution test code in get_min_max_with_quirks(), which may leave the variable untouched, leading to a random uninitialized value, as detected by syzkaller fuzzer. Add the missing return error check for fixing that.
