[PATCH v7 10/47] net/sxe2: clear security context pointer on uninit

[Jie Liu]

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.
