[PATCH v2] ethdev: Align enable logic handling with disable functions

[Sunyang Wu <sunyang.wu@jaguarmicro.com>]

This patch modifies the handling logic of the "enable" related
operations. The key intention is to align it with the processing
approach of the "disable" functions.
Previously, there was an inconsistency in how failure scenarios were
dealt with between the "enable" and "disable" logic. Now, after
adjustment, their behaviors in exceptional cases are made more uniform.
Importantly, this change does not introduce any alteration to the actual
runtime behavior of the functions; it only serves to enhance code
consistency and maintainability, making the overall logic easier to
understand and maintain in the long run.
In this way, we ensure the codebase follows a more cohesive pattern,
reducing potential confusion during future development and maintenance
efforts that could stem from logical disparities.
