xfs: fix rtgroup cleanup in CoW fork repair

Browse Source 
commit c3e0738943 upstream.

xrep_cow_find_bad_rt() initializes scrub rtgroup state before the
force-rebuild path calls xrep_cow_mark_file_range(). If that call
fails, the code jumps directly to out_rtg, which skips the scrub
rtgroup cleanup and only drops the local rtgroup reference.

Remove the unnecessary jump so the function falls through to out_sr,
ensuring the realtime cursors, lock state, and sr->rtg reference are
released before returning.
