Description of problem:

After importing repositories containing modular rpms (AppStream, for example), Satellite shows errata applicable to the host even if the module stream is not enabled on the client.

Version-Release number of selected component (if applicable):

Satellite 6.12

How reproducible:
Always

Steps to Reproduce:
1. Import an AppStream repository into Satellite
2. Register a RHEL8 client and install any module stream rpms ("dnf module install ruby:2.5" for example)
3. Look at the errata and you'll see errata targeting other ruby module streams

Actual results:

Will see some errata that are targeted to module streams that are not enabled on the system.

Expected results:

Only errata targeted to module streams enabled/installed on the client should be listed.
