s390/qeth: allocate a single cmd on read channel We statically allocate 8 cmd buffers on the read channel, when the only IO left that's still using them is the long-running READ. Replace this with a single allocated cmd, that gets restarted whenever the READ completed. This introduces refcounting for allocated cmds, so that the READ cmd can survive the IO completion.
