wifi: rtlwifi: rtl8192se: rise completion of firmware loading as last step

Browse source 
[ Upstream commit 8559a9e0c457729fe3edb3176bbf7c7874f482b0 ]

Just like in commit 4dfde294b979 ("rtlwifi: rise completion at the last
step of firmware callback"), only signal completion once the function is
finished. Otherwise, the module removal waiting for the completion could
free the memory that the callback will still use before returning.

Fixes: b0302aba81 ("rtlwifi: Convert to asynchronous firmware load")
