[SCSI] megaraid_sas: do not process cmds if hw_crit_error is set
Checks if hw_crit_error is set. If it is set, we donot process commands. Checks added in megasas_queue_command and command completion routines. Signed-off-by: Sumant Patro <sumant.patro@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
