This fixes an error introduced in the coredump-header patch in
the coredump removal patch I submitted earlier. It should be squashed
into that patch series so that the Kconfig option to remove coredump
doesn't cause compile-time errors.

v2: Removed an erroneous return statement that shouldn't have gotten into
the original patch. I apologize for the spam

Note to Andrew Morton: This is a small fix of an oversight in the coredump
patch I submitted earlier. Could this be squashed into the others in -mm?
