wifi: rtlwifi: Ignore IEEE80211_CONF_CHANGE_RETRY_LIMITS

Browse source 
Since commit 0a44dfc070 ("wifi: mac80211: simplify non-chanctx
drivers") ieee80211_hw_config() is no longer called with changed = ~0.
rtlwifi relied on ~0 in order to ignore the default retry limits of
4/7, preferring 48/48 in station mode and 7/7 in AP/IBSS.

RTL8192DU has a lot of packet loss with the default limits from
mac80211. Fix it by ignoring IEEE80211_CONF_CHANGE_RETRY_LIMITS
completely, because it's the simplest solution.
