[PATCH v1 2/2] dts: add exception handling to checksum verify method

[Dean Marx <dmarx@iol.unh.edu>]

Current implementation of the checksum offload test suite
contains a section in the verify checksum method
that causes NameError exceptions when the packet is
dropped. Add a try block to encapsulate this section
and handle any errors created.

Fixes: 8c9a7471a0e6 ("dts: add checksum offload test suite")
