rgw: respect location constraint in master zonegroup

rgw: respect location constraint in master zonegroup

When creating a bucket with a location constraint specified by the
user, this constraint is not included in createparams. Therefore,
to create the bucket in the requested location, createparams and
bucket_zonegroup must be replaced with the user-provided values.
