wifi: mt76: testmode: add nla_policy for MT76_TM_ATTR_TX_LENGTH

Browse Source 
[ Upstream commit 74f12d511625e603fac8c0c2b6872e687e56dd61 ]

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.
