scsi: isci: Use proper enumerated type in atapi_d2h_reg_frame_handler

[ Upstream commit e9e9a103528c7e199ead6e5374c9c52cf16b5802 ]

Clang warns when one enumerated type is implicitly converted to another.

drivers/scsi/isci/request.c:1629:13: warning: implicit conversion from
enumeration type 'enum sci_io_status' to different enumeration type
'enum sci_status' [-Wenum-conversion]
                        status = SCI_IO_FAILURE_RESPONSE_VALID;
                               ~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/isci/request.c:1631:12: warning: implicit conversion from
enumeration type 'enum sci_io_status' to different enumeration type
'enum sci_status' [-Wenum-conversion]
                status = SCI_IO_FAILURE_RESPONSE_VALID;
                       ~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

status is of type sci_status but SCI_IO_FAILURE_RESPONSE_VALID is of
type sci_io_status. Use SCI_FAILURE_IO_RESPONSE_VALID, which is from
sci_status and has SCI_IO_FAILURE_RESPONSE_VALID's exact value since
that is what SCI_IO_FAILURE_RESPONSE_VALID is mapped to in the isci.h
file.
