do not define 8-byte alignment for union smcd_cdc_cursor in
patch 4/5 "net/smc: atomic SMCD cursor handling"
v2->v3:
stay with 8-byte alignment for union smcd_cdc_cursor in
patch 4/5 "net/smc: atomic SMCD cursor handling", but get rid of
__packed for struct smcd_cdc_msg
v3->v4:
get rid of another __packed for struct smc_cdc_msg in
patch 4/5 "net/smc: atomic SMCD cursor handling"
