Description of problem:
Creating the tuned profile with the kernel arguments should automatically create a machineconfig resource with specified kernel argument. But it not happen when the master nodes selected as target by the tuned profile.

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-09-16-080214

How reproducible:
Always


Steps to Reproduce:
1. Create the tuned profile specified above
2. Wait for MC creation
3.

Actual results:
MC wasn't created

Expected results:
The MC with relevant parameters should be created.

Additional info:
The cluster has 3 nodes when node both master and worker.
