Anand Lodnoor 1cb14cce72 scsi: megaraid_sas: Do not initiate OCR if controller is not in ready state 
commit 6d7537270e upstream.

Driver initiates OCR if a DCMD command times out. But there is a deadlock
if the driver attempts to invoke another OCR before the mutex lock
(reset_mutex) is released from the previous session of OCR.

This patch takes care of the above scenario using new flag
MEGASAS_FUSION_OCR_NOT_POSSIBLE to indicate if OCR is possible.
