Larry Finger d1cd5ba4ca rtlwifi: rtl8192se: Fix connection problems 
Changes in the vendor driver were added to rtlwifi, but some updates
to rtl8192se were missed, and the driver could neither scan nor connect.
There are other changes that will enhance performance, but this minimal
set fix the basic functionality.
