dpif-netdev: Change a variable name.

'struct dp_netdev_flow' is currently being instantiated as 'flow'.

which uses 'struct flow' at a few places and that can cause
confusion while reading code.

do not report OF1.1 bits (set_dl_src etc) as group features is OF1.2+.

LINC seems to use 1<<31 for experimenter action type but i failed to
