In profinet plugin, there is a dissection based on whether the read data
returned is expected to contain a single or multiple blocks. Currently, the
I&M0FilterData case assumes only a single block is returned. Profinet specifies
two optional additional blocks.

This change moves I&M0FilterData to expect multiple blocks to correct decode
the optional information.
