scsi: bfa: Remove additional unnecessary struct declarations

Commit c3b0d087

 ("scsi: bfa: Remove unnecessary struct declarations")
removed duplicate struct declarations for struct bfa_fcs_s and struct
bfa_fcs_fabric_s.

However, there are further duplications:

 - struct bfad_vf_s is declared in line 165 remove the duplication in line
   834.

 - struct bfad_rport_s is declared in line 394 remove the duplication in
   line 836.

Remove them.
