EDAC/mc: Drop duplicated dimm->nr_pages debug printout

The duplicated edac_dbg()-based dimm->nr_pages print was introduced in

  6e84d359 ("edac_mc: Cleanup per-dimm_info debug messages").

The duplicated line can be found even in the commit message text:

  [ 1011.380101] EDAC DEBUG: edac_mc_dump_dimm:   dimm->nr_pages = 0x40000
  [ 1011.380103] EDAC DEBUG: edac_mc_dump_dimm:   dimm->grain = 8
  [ 1011.380104] EDAC DEBUG: edac_mc_dump_dimm:   dimm->nr_pages = 0x40000

Drop the second edac_dbg() call.
