[patch] rxantenna value is reset after suspend/resume

Description

If diversity is disabled and rxantenna is set to 2, a suspend/resume resets the rxantenna to 1.

I discovered this on the Pepper Pad 3, on which we explicitly disable diversity via sysctl and peg both antennas to 2: 

sysctl dev.wifi0.diverity=0
sysctl dev.wifi0.rxantenna=2
sysctl dev.wifi0.txantenna=2

A customer of ours reported that their pad would only associate with his access point the first time he booted it, but would fail to associate after waking from sleep. This report in turn led to the discovery of this bug.

The attached patch checks to see if the HAL's rxantenna value differs from the driver's saved value on a resume, and if they differ, the saved value is used to reset the rxantenna.
