    umb: Fix setting the input routine

    This driver does not depend on netmap, and umb_input() works greatly
    without netmap.

    Remove the #ifdef DEV_NETMAP so that when "device netmap" is not
    configured this driver can still correctly pass the inbound packets to
    the net stack. Otherwise the input routine will be if_input_default()
    which will silently drop all inbound packets.
