Roel Kluin fb8585fc3f ctcm: avoid wraparound in length of incoming data ...

Since the receive code should tolerate any incoming garbage, it
should be protected against a potential wraparound when manipulating
length values within incoming data.
block_len is unsigned, so a too large subtraction will cause a
wraparound.
