[PATCH] wifi: rtlwifi: rtl8192cu: Remove logically dead code in rtl92cu_update_hal_rate_table

The variable 'mimo_ps' is initialized to IEEE80211_SMPS_OFF and never
modified throughout the function. This makes the condition checking for
IEEE80211_SMPS_STATIC always evaluate to false, rendering the entire
if-branch unreachable dead code.

This error was reported by Coverity Scan.
