net/mlx5e: Propagate the filter's net device to mlx5e structures

Propagate the filter's net_device parameter to the tc flower parsed
attributes structure so that it can later be used in tunnel decap
offloading sequences.

Pre-step for replacing egdev logic with the indirect block
notification mechanism.
