Ruiyu Ni 68b07ebae5 ShellPkg/ShellLib: Fix dynamic command fails to start during boot ... The previous change in ShellLib: "commit 3d29f8c5e3 * ShellPkg/ShellLib: Constructor doesn't depend on ShellParameters" resolved the issue when loading dynamic command driver from Shell environment. But when dynamic command driver is built into FV and started during boot, the driver still fails to start because Shell protocol doesn't exist at that time. The patch changes ShellLib to: 1. Do not look for Shell and ShellParameters protocol when they are non-NULL in ShellLibConstructorWorker(); The two protocols are assumed to be set by DynamicCommand.Handler. When ShellInitialize() is called in DynamicCommand.Handler, this change can prevent the two protocols to be changed to NULL by the locating logic. 2. Do not reset the Shell and ShellParameters protocol to NULL in ShellLibDestructor() when CloseProtocol() fails; Dynamic command driver needs to set the PcdShellLibAutoInitialize to FALSE in order to skip the constructor. Current logic calls ShellLibDestructor() when the PCD is FALSE when ShellInitialize() is called. The change prevent the two protocols to be changed to NULL. The two changes don't impact existing usage case so they are backward compatible.
