Sumit Saxena 6d40afbc7d megaraid_sas: MFI IO timeout handling
This patch will do proper error handling for DCMD timeout failure cases
for Fusion adapters:

1. For MFI adapters, in case of DCMD timeout (DCMD which must return
SUCCESS) driver will call kill adapter.

2. What action needs to be taken in case of DCMD timeout is decided by
function dcmd_timeout_ocr_possible().  DCMD timeout causing OCR is
applicable to the following commands:

	MR_DCMD_PD_LIST_QUERY
	MR_DCMD_LD_GET_LIST
	MR_DCMD_LD_LIST_QUERY
	MR_DCMD_CTRL_SET_CRASH_DUMP_PARAMS
	MR_DCMD_SYSTEM_PD_MAP_GET_INFO
	MR_DCMD_LD_MAP_GET_INFO

3. If DCMD fails from driver init path there are certain DCMDs which
must return SUCCESS. If those DCMDs fail, driver bails out. For optional
DCMDs like pd_info etc., driver continues without executing certain
functionality.
