fix a panic triggerable by anyone with read/write access to the audio
devices. opening /dev/{dsp,dspW,audio}0 and then opening a different device
from that list and closing it resulted in a panic when any operation is
performed on the first fd.
we prevent this happening by denying the second open unless it uses the same
minor device as the first.
