Subject: [edk2] [PATCH] StartCorePkg: Delete redundant 'WaitForRoot'

When using StartCore.efi to test Mp service protocol, there will cause an 
ASSERT. "edk2/MdeModulePkg/Core/Dxe/Mem/Pool.c(439): Head->Size == Tail->Size"

The Reason:
the AP invoked ClientTask() which waited for RootTask() changed the 'Ready' 
Flags to continue, but when 'MaxCount' had consumed, the redundant 
'WaitForRoot' still waited for BSP changing the 'Ready' Flags . while the BSP 
had began to free the 'Tcb' parameters(FreePool( mTcb)) which still be used by 
ClientTask(), so should drop it.
