MdeModulePkg/PciSioSerialDxe: Fix compiler warnings
Add missing braces in module global mControllerDevicePathTemplate. Initialize ControllerNumber and ContainsControllerNode in SerialControllerDriverStart() to address warning for potential use before initialization warning. Move initialization of local SerialIo earlier in SerialControllerDriverStart() to address warning for potential use before initialization warning. (Sync patch r19232 from main trunk.)
