[PATCH v4 13/13] cxl/ras: Make cxl_cper_handle_prot_err() static

The extlog caller went away when extlog switched to
cxl_cper_post_prot_err(), leaving cxl_cper_prot_err_work_fn() in the same
file as the only caller.

Drop the export and the declaration in <cxl/event.h>, and make it static.

v4:
- New patch. The extlog lock inversion fix earlier in the series removes the
  last external caller, leaving the export and the <cxl/event.h> declaration
  dead.
