Description of problem:

Capsule requests lease from Infoblox via its API performing a query to Infoblox which returns a record that has a null value for MAC address which the code does not expect,                                                                                                                                                                 
thus it fails with:
~~~
undefined method `tr' for nil:NilClass
~~~

Version-Release number of selected component (if applicable):
Satellite 6.6

How reproducible:
100%

Steps to Reproduce:
1. Have a lease in dhcp with no mac
2. auto suggest ip for subnet that has infoblox assigned
3.

Actual results:
undefined method `tr' for nil:NilClass


Expected results:
skip the lease that has no mac set.

Additional info:
The following patch skips the lease with empty mac and suggest an ip address:

Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/29640 has been resolved.

Tested on Sat 6.8 Snap 17 using the reproducer from the initial report. No error on getting an unused IP from Infoblox encountered, even with abandoned leases.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
