wifi: mac80211: fix incorrect type for ret

[ Upstream commit a33b375ab5b3a9897a0ab76be8258d9f6b748628 ]

The variable ret is declared as a u32 type, but it is assigned a value
of -EOPNOTSUPP. Since unsigned types cannot correctly represent negative
values, the type of ret should be changed to int.
