    mac80211: rt2x00: improve eeprom_file property handling
    
    Call the rt2x00lib_get_eeprom_file_name only once and from the function
    where the EEPROM filename is required.
    
    Error only out if an EEPROM file is mandatory. Use the
    REQUIRE_EEPROM_FILE bit to determine if it is mandatory.
    
    Do not set the REQUIRE_EEPROM_FILE bit while requesting an EEPROM file.
    It should be (and is) set before requesting an EEPROM file.
    
    Do not redirect users to upstream while using a function of a custom
    patch.
