MFC: r317578
Fix a bug introduced as part of r287726; use the right device_t for
determining the softc of the bridge in psycho_route_interrupt(). [1]
While at it, update the corresponding comment that the code in
question is also necessary for U30s in addition to E450s (a fact
that has been known for ages).
