TLVP_PRESENT() should not return TRUE after tlv_parse() fails.
If the length provided in the patcket exceeds the buffer length,
tlv_parse() returns -2 but leaves tlv.val and tlv.len initializd.
Many callers of tlv_parse() do not check its return value, but
rely on TLVP_PRESENT() to see if a particular TLV was parsed
successfully. By clearing tlv.val and tlv.len we make it less
likely that those callers will use an overlong TLV length value.
