geneve: Zero header before parsing userspace tunneling action.

Browse Source 
When we parse the text representation of the Geneve action the
header is not fully initialized. Besides the obvious potential
to generate an action that the user did not actually specify, this
also causes intermittent unit test failures when an action is
read in and printed out and the result is different.
