[PATCH v6 10/45] net/sxe2: clear security context pointer on uninit

[liujie5 at linkdatatechnology.com]

From: Jie Liu <liujie5 at linkdatatechnology.com>

sxe2_security_uinit() frees the security session but leaves
dev->security_ctx pointing at the freed memory. Set
dev->security_ctx to NULL after releasing the security context
so a later access does not dereference a dangling pointer.
