scsi: zfcp: Enhance fsf status read buffer tracing

SRB trace records are logged through hba trace event zfcp_dbf_hba_fsf_uss.
Presently, this trace event has few missing fields in fsf status read
buffer trace records. To fully trace incoming fsf status read buffer (SRB),
the remaining fields are needed to be added to zfcp_dbf_hba_uss structure.

Append all the remaining SRB fields to the existing unsolicited status
trace records.

Extend driver to get 3 bytes source id s_id value from fsf status read
buffer's existing reserved field res3.

To display this change, we also change the external tool `zfcpdbf` in the
s390-tools package.
