net: mac802154: comparision issue of type cast, finding by EXTRA_CFLAGS=-W Change MAC802154_CHAN_NONE from ~(u8)0 to 0xff, or the comparison in mac802154_wpan_xmit() for ``chan == MAC802154_CHAN_NONE'' will not succeed. This bug can be boiled down to ``u8 foo = 0xff; if (foo == ~(u8)0) [...] else [...]'' where the condition will always take the else branch.
