Do not write ERROR level log entries if debug file is not used

Browse source 
wpa_debug_reopen_file() used to write an error message at MSG_ERROR
level if it was called with last_path == NULL (the last debug log file
path not known). This is not a fatal error, but a normal case if
wpa_debug_open_file() has not been used. Remove the error message and
return success in such case.
