[ Upstream commit da1a039bcf293e4699d413c9f65d975da2d7c0bd ]
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.
