kernel: net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

A flaw was found in the Linux kernel's bpf programs. Under certain conditions, when the kernel attempts to initiate a network connection using the kernelconnect function, it can return a value that causes the cxtcpsetupsocket function to loop. This issue can lead to continuous data writing to the...
