Avoid unnecessary operation of ovsdb and flows
Type of lvm.vlan is int and other_config.get('tag') is a string,
they can never be equal. We should do type conversion before
comparing to avoid unnecessary operation of ovsdb and flows.

Status in neutron:
Fix Released
Bug description:
when restart ovs-agent, br-int lose flows ephemerally due to
unnecessary flow operation.
In _add_port_tag_info[1]，type of lvm.vlan is int and
other_config.get('tag') is a str, they can never be equal. We should
do type conversion for lvm.vlan before comparing to avoid unnecessary
operation of ovsdb and flows.
