[PATCH 2/2] drm/xe/ras: Clean up coding style in xe_drm_ras

[Shuicheng Lin <shuicheng.lin@intel.com>]

- Fix long line in cleanup_node_param() signature.
- Drop unnecessary const on pass-by-value enum parameters.
- Simplify xe_drm_ras_init() by removing redundant local variable
  and redundant error path.

No functional change.
