isdn/gigaset: improve error handling querying firmware version
commit e055d03dc088a990fe5ea24a2d64033a168da23c upstream. An out-of-place "OK" response to the "AT+GMR" (get firmware version) command turns out to be, more often than not, a delayed response to a previous command rather than an actual error, so continue waiting for the version number in that case.
