detect: use u32 for InspectionBufferMultipleForList

So that we do not have an endless loop casting index to
u16 and having more than 65536 buffers in one transaction

Changes for all protocols, even ones where it is impossible
to have such a pattern, so as to avoid bad pattern copy/paste
in the future
