[PATCH] drivers: hwmon: fix device_node_continue.cocci warnings

[Julia Lawall]

Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.

The patch would not be needed if aspeed_create_type etc perform a second
get, beyond the one in the iterator.
