PR #11165 causes an unnecessary regression; task_delete no longer works, if the deleted task is from another group. The logic that prevents this comes from: nxnotify_cancellation() -> tls_get_info_pid() -> nxsched_get_stackinfo() Which checks for permissions, which does not make sense in this case since it is the kernel asking for the stack information. Fix this by partially reverting 11165 and implementing a direct path for the kernel to query for any tasks TLS.
