Because clcsk_*, like clcsock, is initialized during the smc init process, 
the code was moved to prevent clcsk_* from having an address like 
inet_sk(sk)->pinet6, thereby preventing the previously initialized values 
​​from being tampered with.

Additionally, if you don't need alignment in smc_inet6_prot , I'll modify 
the patch to only add the necessary code without alignment.
