System crash, where driver is accessing scsi layer's
memory (scsi_cmnd->device->host) to search for a well known internal
pointer (vha). The scsi_cmnd was released back to upper layer which
could be freed, but the driver is still accessing it.

Remove access of freed memory. Currently the driver was checking to see if
scsi_done was called by seeing if the sp->type has changed. Instead,
check to see if the command has left the  oustanding_cmds[] array as
sign of scsi_done was called.
