MdeModulePkg: TerminalDxe: avoid checking uninitialized variable
The SerialIo->GetControl() function is not required to set the
Control output parameter on error. Make sure we apply the
EFI_SERIAL_INPUT_BUFFER_EMPTY optimization in
TerminalConInTimerHandler() only if the SerialIo->GetControl()
function call set that bit in the Control variable.
(Sync patch r18962 from main trunk.)
