i2c: ismt: Return EMSGSIZE for block reads with bogus length
commit ba201c4f5ebe13d7819081756378777d8153f23e upstream.
Compare the number of bytes actually seen on the wire to the byte
count field returned by the slave device.
Previously we just overwrote the byte count returned by the slave
with the real byte count and let the caller figure out if the
message was sane.
