[SCSI] ipr: Fix for oops following SATA request sense
This patch fixes a problem discovered on a system with some bad SATA devices attached. If a command to a SATAPI device times out and the device gets reset as part of error recovery, its possible that ipr will set err_mask to indicate a device error has occurred. If this happens, a request sense will get issued by libata. Since scsi core thinks this scsi command is now completed, because the device reset handler completed successfully, scsi core will free the associated scsi command, which may cause an oops when that request sense is completed later by ipr. This patch ensures that any commands that get aborted as a result of a device reset set err_mask appropriately so that the request sense does not get sent.
