In _rtl92c_query_rxphystatus(), the return rtl_query_rxpwrpercentage() need to be checked. A proper implementation can be found in _rtl8723be_query_rxphystatus(). Add a value check and set the limit of pwdb_add as 100.

Have you tested on real hardware? Or just guess this is a potential problem? If that is a real problem, please point out what it happens in commit message.

By the way, subject should be "wifi: rtlwifi: ..."
