packets: Fix potential use-after-free in compose_benign_packet().

The second call to ofpbuf_put_zeros() could cause the 'eth' pointer to
be invalidated.

It appears that this does not fix a real bug because the existing callers
all preallocate 128 bytes of tailroom, but the interface doesn't document
that requirement.
