Subject: rgw: append obj: prevent tail from being GC'ed
X-Git-Tag: v14.2.12~131^2

rgw: append obj: prevent tail from being GC'ed

append object tail gets GC'ed otherwise as the state has a manifest similar to
atomic obj processor, but if the manifest exists and the position is correct, it
is not an overwrite and shouldn't be GC'ed
