VPP-45 Fix crash when GRE packet received on new i/f
If a GRE tunnel is created, no other interface added and the GRE tunnel
is not set "up" then a crash occurs on the first packet for this tunnel
because fib_index_by_sw_if_index[] does not yet have a mapping to the fib
the new interface is in. The code to set this is missing from
gre/interface.c
