Subject: [PATCH] net/mlx5: Use common mlx5_same_hw_devs function
JIRA: https://redhat.atlassian.net/browse/RHEL-169055
commit 211de28b1caf51581ba5e0978e83213db4f488c6

net/mlx5: Use common mlx5_same_hw_devs function
Refactor duplicate hardware device comparison code to use the common
mlx5_same_hw_devs() function instead of reimplementing system GUID
comparison logic in multiple places.
This cleanup eliminates code duplication in:
- Bridge representor device comparison.
- TC hardware device comparison.
Using the centralized function improves maintainability and ensures
consistent behavior across the driver.
