Subject: [PATCH net 2/2] net: phy: aquantia: fix applying active_low bit
 after reset

for_each_set_bit was used wrongly in aqr107_config_init() when iterating
over LEDs. Drop misleading 'index' variable and call
aqr_phy_led_active_low_set() for each set bit representing an LED which
is driven by VDD instead of GND pin.

Fixes: 61578f679378 ("net: phy: aquantia: add support for PHY LEDs")
