dpif-linux: Handle nl_lookup_genl_mcgroup() failures.

Browse Source 
The nl_lookup_genl_mcgroup() function can fail on older kernels
which do not support the required netlink interface.  Before this
patch, dpif-linux would refuse to create a datapath when this
happened.  With this patch, it attempts to use a workaround.  If
the workaround fails it simply disables the affected features
without completely disabling the dpif.
