    bhnd: Correct the softc size in the siba_bhndb_driver definition
    
    struct siba_bhndb_softc embeds struct siba_softc and adds an extra
    field, "quirks".  In practice, this bug was harmless since "quirks" is
    unconditionally initialized during driver attach and would have lived in
    the redzone of the softc allocation, but KASAN catches the out-of-bounds
    access.
