Subject: rtlwifi: rtl8192ce: Fix loading of incorrect firmware

From: Jurij Smakov <[email protected]>

commit 52f5631a4c056ad01682393be56d2be237e81610 upstream.

In commit cf4747d7535a ("rtlwifi: Fix regression caused by commit d86e64768859, an error in the edit results in the wrong firmware being loaded for some models of the RTL8188/8192CE. In this condition, the connection suffered from high ping latency, slow transfer rates,
and required higher signal strengths to work at all

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853073,
https://bugzilla.opensuse.org/show_bug.cgi?id=1017471, and
https://github.com/lwfinger/rtlwifi_new/issues/203 for descriptions of the problems. This patch fixes all of those problems.
