sockfs: switch to ->free_inode()

we do have an RCU-delayed part there already (freeing the wq), so it's not like the pipe situation; moreover, it might be worth considering coallocating wq with the rest of struct sock_alloc. ->sk_wq in struct sock would remain a pointer as it is, but the object it normally points to would be coallocated with struct socket...
