[Qemu-block] [PATCH] sheepdog: Fix sd_co_create_opts() memory leaks

[Kevin Wolf]

Both the option string for the 'redundancy' option and the
SheepdogRedundancy object that is created accordingly could be leaked in
error paths. This fixes the memory leaks.

Reported by Coverity (CID 1390614 and 1390641).
