[PATCH 2/2] xfs: fix rtgroup cleanup in CoW fork repair

[Yingjie Gao]

The realtime CoW fork repair scan initializes scrub rtgroup state
before it checks whether the whole mapping should be rebuilt.  That
state includes realtime btree cursors, rtgroup locks, and an extra
sr->rtg reference.

If marking the full mapping fails in the force-rebuild path, the code
jumps directly to out_rtg.  That only drops the local rtgroup reference
and skips the scrub rtgroup cleanup, leaving the cursors, lock, and
sr->rtg reference behind.

Jump to out_sr instead so this error path matches the other failures
after xrep_rtgroup_init().
