 Title: #3976: locations.py: fix divide by 0
Action: opened

PR body:
"""
If all IPA servers (or the first server) of a location have
service weights == 0, the sum of the weights is zero leading
to a division by zero in relative weight calculation.
Detect the situation and set relative weight to 0 in this case.

Fixes: https://pagure.io/freeipa/issue/8135
