Revert "Fix CVE-2012-6703 (integer overflow in ALSA subsystem)"
buffer check was turned into a routine, taken care of by snd_compress_check_input https://github.com/Moyster/android_kernel_m2note/blob/ng-7.1.2/sound/core/compress_offload.c#L496
This reverts commit a1beff31cf3b220b7c983c1933ad5dbd438f89fc.
