Subject: [PATCH] nm: Fix error on SR-IOV
When SR-IOV VF naming scheme is like `ens1f0v0`, nmstate will delete
the VF NM connection when applying this state:
```yml
---
interfaces:
- name: ens1f0
type: ethernet
state: up
ethernet:
sr-iov:
total-vfs: 1
- name: ens1f0v0
type: ethernet
state: up
ipv4:
enabled: false
ipv6:
enabled: false
```
This is because `delete_other_profiles()` is checking
`self._nm_profile()` from active NM profile instead of newly created
one. The fix is using newly created profile `self._nm_simple_conn`.
We also have race problem when activating PF along with VF, PF
activation might delete VF NIC which cause VF activation failed. To
workaround that, we activate PF first via `NmProfile.ACTION_SRIOV_PF`
and wait on it before start VF activation.
Also problem found during SR-IOV investigations is we do extra
un-required modification to `NM.SettingOvsExternalIDs` even it is not
mentioned in desired. We skip overriding `NM.SettingOvsExternalIDs` when
not desired.
Existing test case can cover the use cases.
