net: Fix features skip in for_each_netdev_feature()

[ Upstream commit 85db6352fc8a158a893151baa1716463d34a20d0 ]

The find_next_netdev_feature() macro gets the "remaining length",
not bit index.
Passing "bit - 1" for the following iteration is wrong as it skips
the adjacent bit. Pass "bit" instead.
