rtlwifi: rtl8192de: Fix firmware initialization

commit 0298dc9f2273fb2d596ae10d7700f054bfce601d upstream.

Before the switch to asynchronous firmware loading (mainline commit b0302ab),
it was necessary to load firmware when initializing the first of the units
in a dual-mac system. After the change, it is necessary to load firmware in
both units.
