Don't populate array error_code on the stack but make it static. Makes
the object code smaller by almost 250 bytes:

Before:
   text    data     bss     dec     hex filename
  10366     983       0   11349    2c55 net/dccp/input.o

After:
   text    data     bss     dec     hex filename
  10161    1039       0   11200    2bc0 net/dccp/input.o
