Staging: rt2860: Ported v1.7.1.1 changes into v1.8.0.0, becoming v1.8.1.1

When RaLink released rt2860 v1.7.0.0, it lacked proper support for both WEP
and WPA/WPA2 encryption. Either was possible, but the module had to be
compiled to support only one or the other, never both.

Since the EeePC was the most common device with this hardware (and these
users were complaining to RaLink that WPA/WPA2 encryption didn't work)
RaLink released a fix as an "eeepc-specific" version of this driver, v1.7.1.1

Unfortunately, when v1.8.0.0 was released, this WPA/WPA2 fix was never
included.

What complicates things further is that RaLink has no interest in
continuing work on this Linux driver for their hardware.

This commit ports the changes introduced in v1.7.1.1 into the v1.8.0.0
release, upgrading the kernel's module to v1.8.1.1
