scsi: mpi3mr: Return complete ioc_status for ioctl commands

The driver masked the loginfo available bit in the iocstatus before passing
it to the applications, causing a mismatch in error messages between Linux
and other operating systems.

Modify driver to return unmasked (complete) iocstatus, including the
loginfo available bit, for the MPI commands sent through the ioctl
interface.
