ALSA: control: Avoid kernel warnings from tlv ioctl with numid 0
commit c0bcdbdff3ff73a54161fca3cb8b6cdbd0bb8762 upstream.
When a TLV ioctl with numid zero is handled, the driver may spew a
kernel warning with a stack trace at each call. The check was
intended obviously only for a kernel driver, but not for a user
interaction. Let's fix it.
This was spotted by syzkaller fuzzer.
