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.
