drm/xe: Replace deprecated DRM_ERROR()

DRM_ERROR() has been deprecated in favor of pr_err(). However, we should
prefer to use xe_gt_err() or drm_err() whenever possible so we get gt-
or device-specific output with the error message.

v2:
  - Prefer drm_err() over pr_err(). (Matt, Jani)
v3:
  - Prefer xe_gt_err() over drm_err() when possible. (Matt)
v4:
  - Use the already available dev variable instead of xe->drm as
    parameter to drm_err(). (Matt)
