[PATCH] EDAC: Use kcalloc()

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

It is syntactic sugar anyway:

  # drivers/edac/edac_mc.o:

   text    data     bss     dec     hex filename
  13378     324       8   13710    358e edac_mc.o.before
  13378     324       8   13710    358e edac_mc.o.after

md5:
   70a53ee3ac7f867730e35c2be9110748  edac_mc.o.before.asm
   70a53ee3ac7f867730e35c2be9110748  edac_mc.o.after.asm

  # drivers/edac/edac_device.o:

   text    data     bss     dec     hex filename
   5684     120       4    5808    16b0 edac_device.o.before
   5684     120       4    5808    16b0 edac_device.o.after

md5:
   811325c80acb5a1d6df7b290df3e1636  edac_device.o.before.asm
   811325c80acb5a1d6df7b290df3e1636  edac_device.o.after.asm

No functional changes.
