Peter Oberparleiter 83b3370c79 [S390] cio: replace subchannel evaluation queue with bitmap 
Use a bitmap for indicating which subchannels require evaluation
instead of allocating memory for each evaluation request. This
approach reduces memory consumption during recovery in case of
massive evaluation request occurrence and removes the need for
memory allocation failure handling.
