When test runs on a SmartSwitch DPU, the exposed mgmt interface is the switch mgmt IP with a NAT port. And it's IPv4 only for now.

Description of PR
Summary:
When test runs on a SmartSwitch DPU(with the DPU host as the host-pattern in the pytest command), the exposed mgmt interface is the switch mgmt IP with a NAT port. And it's IPv4 only for now.
So we need return the switch IP directly instead of getting the IP of "eth0"(which also not exist in a DPU).
Type of change
Back port request
Approach
What is the motivation for this PR?
Update the get_mgmt_ip in sonic host for SmartSwitch DPU
How did you do it?
Return the switch IP directly when it's DPU.
How did you verify/test it?
Run the test platform_tests/api/test_watchdog.py on a DPU host-pattern, all passed.
Any platform specific information?
Only for smartswitch
Supported testbed topology if it's a new test case?
