File check_net_oldname.patch of Package virt-v2v

In some network configurations (e.g. macvtap), it is possible to see the
following error during the conversion:

Use of uninitialized value $oldname in concatenation (.) or string at
 /usr/lib/perl5/vendor_perl/5.18.2/Sys/VirtConvert/Config.pm line 489.

Prevent the error by ensure $oldname and $oldtype are defined before
attempting to use them.
