net/smc: fix structure size
The struct smc_cdc_msg must be defined as packed so the size is 44 bytes. And change the structure size check so sizeof is checked. Signed-off-by: Karsten Graul <kgraul@linux.ibm.com> Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
