<!--- Also test if the latest release and devel branch are affected too -->
<!--- Complete *all* sections as described, this form is processed automatically -->

##### SUMMARY
<!--- Explain the problem briefly below -->
Customize Windows 10 guest OS with wait_for_customzation parameter set, but after many hours there is no return and the playbook just stuck there.
##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
vmware_guest
##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
ansible 2.10.0.dev0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /root/.local/lib/python2.7/site-packages/ansible
  executable location = ./bin/ansible
  python version = 2.7.15+ (default, Jul  9 2019, 16:51:35) [GCC 7.4.0]
```

##### CONFIGURATION

```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->
vSphere 6.7U3, Windows 10 guest OS 32bit with BIOS firmware

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->

<!--- Paste example playbooks or commands between quotes below -->
```yaml

```

<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
If something wrong with the customization in guest OS, no event in VC, then wait_for_customization should return timeout error in a not very long time.

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->
no timeout error return after more than 10 hours, just stuck there.
<!--- Paste verbatim command output between quotes -->
