s390/sclp: reduce dependency on event type masks The event type masks can change asynchronously. These changes are reported by SCLP to the OS by state-change events which are retrieved with the read event data command. The SCLP driver has a request queue, there is a window where the read event data request has not completed yet but the SCLP console drivers are trying to queue output requests. As the masks are not updated yet the requests are discarded. The simplest fix is to queue the console requests independent of the event type masks and rely on SCLP to return with an error code if a specific event type is not available.
