bhnd: Correct the softc size in the siba_bhndb_driver definition

Browse source 
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.
