Don't dereference the pointer whose allocation failed

Flagged by cppcheck 1.64:
[app/xkbcomp/keycodes.c:264] -> [app/xkbcomp/keycodes.c:262]:
 (warning) Possible null pointer dereference: new - otherwise it
           is redundant to check it against null.
[app/xkbcomp/keytypes.c:600] -> [app/xkbcomp/keytypes.c:597]:
 (warning) Possible null pointer dereference: old - otherwise it
           is redundant to check it against null.
