All fields of the kek_mgmt_req structure have the type __le32. So make
sure to use cpu_to_le32() to initialize them. This suppresses the sparse
warning:

warning: incorrect type in assignment (different base types)
   expected restricted __le32 [addressable] [assigned] [usertype] new_curidx_ksop
   got int

Fixes: 5860992db55c ("[SCSI] pm80xx: Added SPCv/ve specific hardware functionalities and relevant changes in common files")
