Fix two error handling paths in CoW fork repair.

Patch 1 makes xrep_cow_find_bad() return saved errors after cleanup.
It also lets a force-rebuild bitmap error fall through to the cleanup
labels instead of returning directly.

Patch 2 applies the same fall-through pattern to the realtime helper
so that scrub rtgroup state is released before returning.

Changes since v2:
  - Drop the braces around the single-statement force-rebuild if bodies
    in both patches.

v2:

Changes since v1:
  - Let the force-rebuild error paths fall through instead of adding
    gotos, as Carlos pointed out.
