In StandaloneMM mode, IsStatusCodeUsingSerialPort is expecting to find gMmStatusCodeUseSerialHobGuid, and will assert if it is not found. Change the logic so that if the Guided Hob is not found, to let the function return FALSE and progress to proceed. Signed-off-by: Aaron Pop <aaronpop@microsoft.com>
