openvswitch: Fix vport_send double free

Browse Source 
Today vport-send has complex error handling because it involves
freeing skb and updating stats depending on return value from
vport send implementation.
This can be simplified by delegating responsibility of freeing
skb to the vport implementation for all cases. So that
vport-send needs just update stats.

Fixes: 91b7514cdf ("openvswitch: Unify vport error stats
handling")
