rtwn: fix RTL8192EU power-down / power-up hanging
The RTL8192EU NIC (on older USB 2/USB 3 ports, not on newer
USB 3 ports, that still needs to be fixed!) will attach, scan,
associate fine. However, restarting wpa_supplicant results in the
NIC hanging until you disconnect it.
It turns out early in the power_on sequence - BUT only after a
power_off - the NIC would suddenly stop responding to any USB
transfers. It doesn't require the MCU to be available for USB
transfers - the hardware itself does that - so something had to be
going very sideways.
I traced it down to these steps during the power_off sequence.
They don't exist in the Linux rtl8xxxu driver, and there are commits
earlier in their RTL8192EU bring-up that suggest the author was
facing similar power sequencing / re-sequencing issues.
This likely won't fix the actual channel programming /
power sequencing / deafness issues on later USB-3 ports.
There are other commits / fixes in the rtl8xxxu driver related to
RTL8192EU bring-up that we don't have.

rtwn: Restore RF_ENV control type after initializing RF.
Both rwlwifi in Linux and rtwn in OpenBSD restore this register,
and the existing code was saving the value and not using it.
