[BUG]V4.10.2 rpc_client.go Call function easily happen RWMutex‘s read lock re-entry then deadlock

[yuan0763]

example：

type TestService struct {
}

func (s *TestService) FuncA() error {
//rpc call 127.0.0.1 node's funcB
client.DefaultClient.Call(
context.Background(),
client.NewRequest("TestService", "TestService.FuncB", nil),
nil,
client.WithAddress("127.0.0.1:8080"),
)
return nil
}

func (s *TestService) FuncB() error {
//get the rpcClient's write lock
go func() {
client.DefaultClient.Init()
}()
//rpc call 127.0.0.1 node's funcC,
//rpcClient's mu read lock re-entry then deadlock
client.DefaultClient.Call(
context.Background(),
client.NewRequest("TestService", "TestService.FuncC", nil),
nil,
client.WithAddress("127.0.0.1:8080"),
)
return nil
}

func (s *TestService) FuncC() error {
return nil
}

func TestRpcClient(t *testing.T) {
s := &TestService{}

go func() {
	s.FuncA()
}()

time.Sleep(time.Minute)
