Add recovery function for REWIND/LOCATE failure on tape job.

System: z/OS

Actor : user needing stronger fault tolerance

Description: One of the reason why our customer uses z/OS is its storng fault tolerance. Especially, in multi-path einvironment they expect that I/O job will normally continue its process even in case of one path failure. But current z/OS sometimes make tape I/O job abend in several hardware error cases which is still something recoverable. z/OS can have more storong fault tolerance for that cases.
