scsi: core: Add a precondition check in scsi_eh_scmd_add()
Calling scsi_eh_scmd_add() may cause the error handler never to be woken up
because this may result in shost->host_failed to become larger than
scsi_host_busy(shost). Hence complain if scsi_eh_scmd_add() is called after
SCMD_STATE_INFLIGHT has been cleared.
