sfc: validate MAE action order
Currently the only actions supported are COUNT and DELIVER, which can only
happen in the right order; but when more actions are added, it will be
necessary to check that they are only used in the same order in which the
hardware performs them (since the hardware API takes an action *set* in
which the order is implicit). For instance, a VLAN pop must not follow a
VLAN push. Most practical use-cases should be unaffected by these
restrictions.
Add a function efx_tc_flower_action_order_ok() that checks whether it is
appropriate to add a specified action to the existing action-set.
