QuarkSocPkg/QncSmmDispatcher: Fix use after free issue
Update Quark North Cluster SMM dispatcher logic to handle case where an SMI handler unregisters itself. https://bugzilla.tianocore.org/show_bug.cgi?id=51 This issue was reproduced using the unit test at: https://github.com/mdkinney/edk2/tree/Bug51/Reproduce An ASSERT() is generated the 4th time the periodic SMI handler is triggered when the periodic SMI handler unregisters itself. After applying this patch, the DEBUG() message from the periodic SMI handler in this unit test is generated 4 times, the periodic SMI handler is unregistered, and the UEFI Shell works as expected.
