af_unix: Reject SIOCATMARK on non-stream sockets

In the Linux kernel, the following vulnerability has been resolved:

af_unix: Reject SIOCATMARK on non-stream sockets

SIOCATMARK reports whether the receive queue is at the urgent mark for
MSG_OOB.

In AF_UNIX, MSG_OOB is supported only for SOCK_STREAM sockets.
SOCK_DGRAM and SOCK_SEQPACKET reject MSG_OOB in sendmsg() and recvmsg(),
so they should not support SIOCATMARK either.

Return -EOPNOTSUPP for non-stream sockets before checking the receive
queue.
