Subject: net/mlx5e: Pass actions param to actions_match_supported()
Patch-mainline: v5.18-rc1
Git-commit: 0610f8dc0309cd0ea017d129efb95a942325344d
References: jsc#PED-1549

Currently the mlx5_flow object contains a single mlx5_attr instance.
However, multi table actions (e.g. CT) instantiate multiple attr instances.

Currently action_match_supported() reads the actions flag from the
flow's attribute instance. Modify the function to receive the action
flags as a parameter which is set by the calling function and
pass the aggregated actions to actions_match_supported().
