audit: handle unknown status requests in audit_receive_msg()
Currently, audit_receive_msg() ignores unknown status bits in AUDIT_SET
requests, incorrectly returning success to newer user space tools
querying unsupported features. This breaks forward compatibility.
Fix this by defining AUDIT_STATUS_ALL and returning -EINVAL if any
unrecognized bits are set (s.mask & ~AUDIT_STATUS_ALL).
This ensures invalid requests are safely rejected, allowing user space
to reliably test for and gracefully handle feature detection on older
kernels.
