[PATCH 3/6] USB: remove references to dev.power.power_state

This patch (as891) removes two unnecessary references to
intf->dev.power.power_state from usb-storage, and replaces a reference
to root_hub->dev.power.power_state with a check of root_hub->state.
This is in preparation for the removal of dev.power.power_state, which
is already deprecated.
