[Patch] BluetoothServer.cpp: fix gcc6 build

[mt]

In BluetoothServer::QuitRequested(), gcc6 x86_64 stops build with invalid conversion error, I think RemoveItemAt() may be used instead of RemoveItem() here.

C++ /home/haiku/haiku/haiku/generated64/objects/haiku/x86_64/release/servers/bluetooth/BluetoothServer.o 
/home/haiku/haiku/haiku/src/servers/bluetooth/BluetoothServer.cpp: In member function 'virtual bool BluetoothServer::QuitRequested()':

   fLocalDevicesList.RemoveItem((int32)0)) != NULL)

Is "(int32)" still required?
