[LTP] [PATCH 2/2] rpc/rpc-tirpc: Fix compile error on clang when using registerrpc

[Yang Xu]

When clang upgrade to 16.0.0-2.fc38, these case will report
incompatible-function-pointer-types  error as below:

rpc_registerrpc.c:72:4: error: incompatible function pointer types passing
'bool_t (XDR *, int *)' (aka 'int (struct __rpc_xdr *, int *)') to parameter
of type 'xdrproc_t' (aka 'int (*)(struct __rpc_xdr *, ...)') [-Wincompatible-function-pointer-types]
xdr_int);

the registerrpc declare as below:

int registerrpc(int, int, int, char *(*)(char [UDPMSGSIZE]),
    xdrproc_t, xdrproc_t);

so we should add xdrproc_t cast to avoid this.
