wifi: mt76: fix coverity overrun-call in mt76_get_txpower()
[ Upstream commit03dd0d49de
] Make sure the nss is valid for nss_delta array. Return zero if the index is invalid. Coverity message: Event overrun-call: Overrunning callee's array of size 4 by passing argument "n_chains" (which evaluates to 15) in call to "mt76_tx_power_nss_delta". int delta = mt76_tx_power_nss_delta(n_chains); Fixes:07cda40630
