[virt-manager][PATCH] py3: store exception variables for use outside except

[Cédric Bosdonnat <cbosdonnat@xxxxxxxx>]

In python3 exceptions aren't defined outside the except block. Leading
to 'UnboundLocalError: local variable 'e' referenced before assignment'
errors.

To work around this, store the local variable into one that will have a
longer life.
