net/passt: Remove unused "err" from passt_vhost_user_event() (CID 1612375)

The "err" variable was declared but never used within the
passt_vhost_user_event() function. This resulted in a dead code
warning (CID 1612375) from Coverity.

Remove the unused variable and the associated error block
to resolve the issue.
