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.
