RDMA/mlx5: Allow creating a matcher for a NIC TX flow table

Browse Source 
Currently a matcher can only be created and attached to a NIC RX flow
table. Extend it to allow it on NIC TX flow tables as well.

In order to achieve that, we:

1) Expose a new attribute: MLX5_IB_ATTR_FLOW_MATCHER_FLOW_FLAGS.
   enum ib_flow_flags is used as valid flags. Only
   IB_FLOW_ATTR_FLAGS_EGRESS is supported.

2) Remove the requirement to have a DEVX or QP destination when creating a
   flow. A flow added to NIC TX flow table will forward the packet outside
   of the vport (Wire or E-Switch in the SR-iOV case).
