Description of problem:
Even when User quota is set less than 1K, user info displays 1K

Version-Release number of selected component (if applicable):
ceph version 10.2.3-8.el7cp

How reproducible:
Always

Steps to Reproduce:
1.Set user quota to 1B
$sudo radosgw-admin quota enable --quota-scope=user --uid=redhat2
$sudo radosgw-admin quota set --quota-scope=user --uid=redhat2 --max-size=1B

2.Display user info
$sudo radosgw-admin user info --uid=redhat2


Actual results:
{
    "user_id": "redhat2",
    "display_name": "redhat2",
    "email": "",
    "suspended": 0,
    "max_buckets": 1000,
    "auid": 0,
    "subusers": [],
    "keys": [
        {
            "user": "redhat2",
            "access_key": "M5DXBUYGGMPRSHYPN5O6",
            "secret_key": "K7FpRDoWAwCl0QBwnPBJDODaQwnsD8GqeDipCCJb"
        }
    ],
    "swift_keys": [],
    "caps": [],
    "op_mask": "read, write, delete",
    "default_placement": "",
    "placement_tags": [],
    "bucket_quota": {
        "enabled": false,
        "max_size_kb": -1,
        "max_objects": -1
    },
    "user_quota": {
        "enabled": true,
        "max_size_kb": 1,
        "max_objects": -1
    },
    "temp_url_keys": []
}



Expected results:
max_size_kb in user_quota should not be 1 as it has been set to 1B
