af_llc: fix if-statement empty body warning
When debugging via dprintk() is not enabled, make the dprintk() macro be an empty do-while loop, as is done in <linux/sunrpc/debug.h>. This fixes a gcc warning when -Wextra is set: ../net/llc/af_llc.c:974:51: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] I have verified that there is not object code change (with gcc 7.5.0).
