    if_bridge: Mask MEXTPG if some members don't support it
    
    Similar to how the network stack needs to use mb_unmapped_to_ext() to
    convert mbufs before passing them to an unsupported driver, if_bridge
    needs to avoid passing M_EXTPG mbufs to interfaces that don't support
    them.  Thus, clear IFCAP_MEXTPG on the bridge if any member interfaces
    don't handle unmapped mbufs.
