net/mlx5e: Remove output device parameter from create encap header helpers definition
Passing output device parameter to the helper functions that deal with creation of encapsulation headers is redundant. Output device parameter can be defined inside those helpers, no need to pass it. Refactor the code by removing the parameter from the function signature. This patch doesn't change any functionality.
