[PATCH] dccp: make const array error_code static

From: Colin King
Date: Thu Jul 13 2017 - 07:22:34 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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
