[ Upstream commit 86aab09a4870bb8346c9579864588c3d7f555299 ]
GCC complains about empty macros in an 'if' statement, so convert them to 'do {} while (0)' macros.
Fixes these build warnings:
net/dccp/output.c: In function 'dccp_xmit_packet': ../net/dccp/output.c:283:71: warning: suggest braces around empty body in an 'if' statement [-Wempty-body] 283 | dccp_pr_debug("transmit_skb() returned err=%d\n", err); net/dccp/ackvec.c: In function 'dccp_ackvec_update_old': ../net/dccp/ackvec.c:163:80: warning: suggest braces around empty body in an 'else' statement [-Wempty-body] 163 | (unsigned long long)seqno, state);
