uapi: fix linux/rds.h userspace compilation error

On the kernel side, sockaddr_storage is #define'd to __kernel_sockaddr_storage. Replacing struct sockaddr_storage with struct __kernel_sockaddr_storage defined by <linux/socket.h> fixes the following linux/rds.h userspace compilation error:

/usr/include/linux/rds.h:226:26: error: field 'dest_addr' has incomplete type
struct sockaddr_storage dest_addr;
