Ping-Ke Shih efeae5f497 wifi: mac80211: don't return unset power in ieee80211_get_tx_power()
[ Upstream commit e160ab85166e77347d0cbe5149045cb25e83937f ]

We can get a UBSAN warning if ieee80211_get_tx_power() returns the
INT_MIN value mac80211 internally uses for "unset power level".

 UBSAN: signed-integer-overflow in net/wireless/nl80211.c:3816:5
 -2147483648 * 100 cannot be represented in type 'int'
 CPU: 0 PID: 20433 Comm: insmod Tainted: G        WC OE

In this case, simply return an error instead, to indicate
that no data is available.
