virtio: fix the initialization

Browse Source 
Type: fix

Fixes: d96b28ac09 ("virtio: improve input node performance")

vlib_buffer_t is defined on stack to be used for input feature arc
lookup once per frame call for performance reasons. The definition
is missing the initialization to avoid the assignment of garbage value.
