[SCSI] megaraid_sas: Dont load DevHandle unless FastPath enabled
The following patch for megaraid_sas will fix an issue where the driver should not be loading the DevHandle unless FastPath is enabled. If FastPath was not enabled, this means the hardware raid map validation failed for some reason, or the map was corrupted, which could mean the DevHandle could be invalid.
