[SCSI] zfcp: Move debug data from zfcp_data to own data structure
The struct zfcp_adapter includes everything related to the debug traces. This introduces dependences between the definitions in zfcp_def.h and zfcp_dbf.h. Move all debug related data structures to a new data structure to break those dependencies and manage the debug data in zfcp_dbf.[hc].
