[PATCH net-next] mt76: mt7615: Remove set but unused variable 'index'

[Wang Hai]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/mediatek/mt76/mt7615/testmode.c: In function 
mt7615_tm_set_tx_power
drivers/net/wireless/mediatek/mt76/mt7615/testmode.c:83:7: warning: variable 
‘index’ set but not used [-Wunused-but-set-variable]=

commit 4f0bce1c8888 ("mt76: mt7615: implement testmode support")
involved this unused variable, remove it.
