rgw: add test case to reproduce bucket check stats bug for versioned bucket

Reproduces a regression where radosgw-admin bucket check incorrectly counts
objects that started as unversioned and later transitioned to versioned.

rgw: radosgw-admin bucket check should only print index entries with --check-objects flag

Printing all index entries can be very time consuming for large
buckets and the inability to switch this behavior off makes it
cumbersome to use the command for fixing bucket stats. This was
also preventing the command from outputting recalculated bucket
stats when the --fix flag wasn't specified.

rgw: prevent another leftover bucket index olh entry scenario

If a call to bucket_index_link_olh or bucket_index_unlink_instance
fails, its associated pending xattr may have prevented the olh object
from being removed by another thread. We should do a best effort
cleanup attempt for this case by calling update_olh before returning
an error to the caller.
