sheepdog: Remove unnecessary NULL check in sd_prealloc()

In commit 8b9ad56e9cbfd852a, we removed the code that could result
in our getting to sd_prealloc()'s out_with_err_set label with a
NULL blk pointer. That makes the NULL check in the error-handling
path unnecessary, and Coverity gripes about it (CID 1390636).
Delete the redundant check.
