ipv6/exthdrs: strict Pad1 and PadN check
The following tightens the padding check from commit
c1412fce7eccae62b4de22494f6ab3ff8a90c0c6 :
* Take into account combinations of consecutive Pad1 and PadN.
* Catch the corner case of when only padding is present in the
header, when the extention header length is 0 (i.e., 8 bytes).
In this case, the header would have exactly 6 bytes of padding:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
: Next Header : Hdr Ext Len=0 : :
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +
: Padding (Pad1 or PadN) :
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
