ALSA: pcm: Fix UAF in snd_pcm_oss_get_formats()
commit 01c0b4265cc16bc1f43f475c5944c55c10d5768f upstream.
snd_pcm_oss_get_formats() has an obvious use-after-free around
snd_mask_test() calls, as spotted by syzbot. The passed format_mask
argument is a pointer to the hw_params object that is freed before the
loop. What a surprise that it has been present since the original
code of decades ago...
