rtlwifi: rtl8192c-common: rtl8192ce: Fix for HT40 regression

The changes that were made to rtl8192ce when rtl8192cu was added broke
HT40. The errors included a typo in rtlwifi, a missing routine in
rtl8192ce and a missing callback of that routine in rtl8192c-common.

This patch fixes the regression reported in Bug #35082.
