Description of problem:

The 'Boot time' and 'kernel version' fields are blank for some of the hosts registered with Satellite 6.17

How reproducible: Intermittently

Is this issue a regression from an earlier version: Not Sure

Steps to Reproduce:

1. Register hosts to Satellite

2. Run the following command on Registered Hosts: ` # subscription-manager facts --update`

3. Navigate to Satellite Web UI -> All Hosts -> click on registered host

Actual behavior:
The 'Boot time' and 'kernel version' fields are empty for some of the hosts

Expected behavior:
The 'Boot time' and 'kernel version' fields should get reflected for the registered host

Workaround:

   **   (1) Satellite Web UI -> All Hosts -> click on affected host `clientVM.example.com` -> Select "Cancel Build" in the menu located at top right corner

   (2) Execute the below command on affected host:

       # subscription-manager facts --update

       # subscription-manager refresh --force

After following above steps, the  'Boot time' and 'kernel version' fields are rightly reflected for the registered hosts on Satellite WebUI
