wifi: mt76: testmode: add nla_policy for MT76_TM_ATTR_TX_LENGTH

It seems that the nla_policy in mt76_tm_policy is missed for attribute MT76_TM_ATTR_TX_LENGTH. This patch adds the correct description to make sure the u32 val = nla_get_u32(tb[MT76_TM_ATTR_TX_LENGTH]); in function mt76_testmode_cmd() is safe and will not result in out-of-attribute read. Fixes: f0efa86 ("mt76: add API for testmode support") Signed-off-by: Lin Ma <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
