chelsio/chtls: fix writing freed memory 



When chtls_sock *csk is freed, same memory can be allocated
to different csk in chtls_sock_create().
csk->cdev = NULL; statement might ends up modifying wrong
csk, eventually causing kernel panic.
removing (csk->cdev = NULL) statement as it is not required.
