Fix for PR kern/38273

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

Juan RP suggested a simple fix for PR kern/38273:

 -       mutex_init(&sc->sc_mutex, MUTEX_DEFAULT, IPL_VM);
 +       mutex_init(&sc->sc_mutex, MUTEX_DEFAULT, IPL_NONE);

  
         if ((sc->sc_flags & LDF_ENABLED) == 0) {
                 aprint_normal_dev(sc->sc_dv, "disabled\n");

Considering that other pseudo drivers (e.g. raid(4)) use IPL_NONE, too,
this seems to be reasonabl to me.

Any comments?

        Kind regards
