[SCSI] megaraid: simplify internal command handling
We don't use the passed in scsi command for anything, so just add a adapter- wide internal status to go along with the internal scb that is used unter int_mtx to pass back the return value and get rid of all the complexities and abuse of the scsi_cmnd structure. This gets rid of the only user of scsi_allocate_command/scsi_free_command, which can now be removed.
