Remove a needless memset() in get_token_arguments()

Browse source 
I believe we originally added this for "just in case" safety, but it
isn't actually needed -- we never copy uninitialized stack here.
What's more, this one memset is showing up on our startup profiles,
so we ought to remove it.

Closes ticket 28852.
