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.
