Modified Files:
        src/sys/dev/dkwedge: dk.c

Log Message:
dk(4): Strengthen dkclose preconditions.

Like dkopen, except it is possible for this to be called after the
wedge has transitioned to dying.

XXX sc_state read here races with sc_state write in dkwedge_detach.
Could change this to atomic_load/store.
