T2-VOQ-VS: Modified exception handling due to new sonic_platform pack…

…age support for VS (sonic-net#3250)

### What I did
For T2-Chassis VS support, we are adding new sonic_platform package for vs platforms. Please refer sonic-net/sonic-buildimage#18512 for more details.
Due to this new platform package, need to modify excpetion handling as now the Module would be found, but the metadata file will not be found for pizzabox vs platforms.

#### How I did it
Modified the exception handling logic.
MSFT ADO: 27414904

#### How to verify it
Bring up vms-kvm-t0 topology. ran show interface status. The output is proper.

PS: the Main PR(sonic-net/sonic-buildimage#18512) is dependent on this PR to be merged in first.
