Place the macro arguments within parentheses to avoid precedence issues.
This solves the following checkpatch.pl warnings
CHECK: Macro argument 'len' may be better as '(len)' to avoid precedence issues
+#define ND_NLMSG_S_LEN(len) (len + ND_IFINDEX_LEN)
CHECK: Macro argument 'nlh' may be better as '(nlh)' to avoid precedence issues
+#define ND_NLMSG_R_LEN(nlh) (nlh->nlmsg_len - ND_IFINDEX_LEN)
