ALSA: pcm: oss: Fix potential out-of-bounds shift
syzbot spotted a potential out-of-bounds shift in the PCM OSS layer
where it calculates the buffer size with the arbitrary shift value
given via an ioctl.
Add a range check for avoiding the undefined behavior.
As the value can be treated by a signed integer, the max shift should
be 30.
