Subject: [PATCH 4/5] scsi: megaraid_sas - Add three times Online controller
 reset

RE-SUBMIT: I am re-attaching the patch:

If fw didn't raise the interrupt with the fw state change to driver
and fw goes to failure state, driver Will check the FW state in
driver's timeout routine and issue the reset if need.  Driver will do
the OCR upto three times until kill adapter.  Also driver will issue
OCR before driver kill adapter even if fw in operational state.
