[SCSI] zfcp: remove unused references, declarations and flags
- Remove unused references and declarations, including one instance
of the FC ls_adisc struct that has been defined twice.
- Also remove the flags COMMON_OPENING, COMMON_CLOSING,
ADAPTER_REGISTERED and XPORT_OK that are only set and cleared, but
not checked anywhere.
- Remove the zfcp specific atomic_test_mask makro. Simply use
atomic_read directly instead.
- Remove the zfcp internal sg helper functions and switch the places
where it is still used to call sg_virt directly.
- With the update of the QDIO code, the QDIO data structures no
longer use the volatile type qualifier. Now we can also remove the
volatile qualifiers from the zfcp code.
