Log Message:
dk(4): Omit needless sc_iopend, sc_dkdrn mechanism.
vdevgone guarantees that all instances are closed by the time it
returns, which in turn guarantees all I/O operations (read, write,
ioctl, &c.) have completed, and, if the block device is open,
vinvalbuf(V_SAVE) -> vflushbuf has completed, which forces all
buffered transfers to be issued and waits for them to complete.
So by the time vdevgone returns, no further transfers can be
submitted and the bufq must be empty.
