22f9934767 [S390] qdio: rework debug feature logging 
- make qdio_trace a per device view
- remove s390dbf exceptions
- remove CONFIG_QDIO_DEBUG, not needed anymore if we check for the level
  before calling sprintf
- use snprintf for dbf entries
- add start markers to see if the dbf view wrapped
- add a global error view for all queues

Improve s390 debug feature usage:
- log busy bit in dbf
- increase size of dbf views
- consistent logging of qdio api calls to setup view
- print subchannel number so one can associate the interface
  with the dbf data
- only log events to one view
