L3Out Loopback IP Overlap With L3Out Interfaces not showing valid results

[almo-ina]

Pre-upgrade validation script is showing the test 41/67 with invalid output that seems misleading as it doesn't mention any IPs or where to start looking for the issue.

Script output

[Check 41/67] L3Out Loopback IP Overlap With L3Out Interfaces...
Error: invalid literal for int() with base 16: '1/128'...

To Reproduce
I trust you will need to have IPv6 as loopback with /128

Expected behavior

If this is a true issue, then at least the script should tell us where to find the issue.

Additional context
node-1# moquery l3extLoopBackIfP | grep dn | grep /128
dn : uni/tn-ADM/out-cr_bgp_de1crt01-1/lnodep-1207-1208/rsnodeL3OutAtt-[topology/pod-2/node-1207]/lbp-[2a01:887:190f:2::1/128]

However, in the ip_in_subnet class method, we never split it, which leads to the error.
