ca8210: Fix unsigned mac_len comparison with zero in ca8210_skb_tx()
commit 748b2f5e82d17480404b3e2895388fc2925f7caf upstream.
mac_len is of type unsigned, which can never be less than zero.
mac_len = ieee802154_hdr_peek_addrs(skb, &header);
if (mac_len < 0)
return mac_len;
Change this to type int as ieee802154_hdr_peek_addrs() can return negative
integers, this is found by static analysis with smatch.
