tg3: Fix some checkpatch errors

This patch fixes the following checkpatch errors:

ERROR: do not use assignment in if condition
+	if ((mss = skb_shinfo(skb)->gso_size) != 0) {

ERROR: do not use assignment in if condition
+	if ((mss = skb_shinfo(skb)->gso_size) != 0) {

ERROR: space prohibited after that '!' (ctx:BxW)

ERROR: "(foo*)" should be "(foo *)"
+		memcpy(data, ((char*)&val) + b_offset, b_count);

ERROR: do not use assignment in if condition
