    openvswitch: change type of UPCALL_PID attribute to NLA_UNSPEC

    userspace openvswitch patch "(dpif-linux: Implement the API
    functions to allow multiple handler threads read upcall)"
    changes its type from U32 to UNSPEC, but leave the kernel
    unchanged

    and after kernel 6e237d099fac "(netlink: Relax attr validation
    for fixed length types)", this bug is exposed by the below
    warning

    	[   57.215841] netlink: 'ovs-vswitchd': attribute type 5 has an invalid length.
