Do not try to re-use net_context.user_data field as in many places (like in accept) it is expected to contain pointer to net_context. Storing the socket flags will corrupt the value. To simplify and make things less error prone, use socket specific field in net_context to store the socket flags. Fixes #19191 Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>
