EDAC: Mark edac_create_debug_nodes as static

This patch marks the function edac_create_debug_nodes() as static
because it is not used outside of edac_mc_sysfs.c.

Thus, it also eliminates the following warning:
drivers/edac/edac_mc_sysfs.c:917:5: warning: no previous prototype for ‘edac_create_debug_nodes’ [-Wmissing-prototypes]
