QuarkSocPkg/QNCSmmDispatcher: Fix use after free issue #2 

As part of commit 5f82e02, ActiveRecordInDb was introduced as a copy
of RecordInDb as latter may be freed by the callback function. This
commit replaces an access of RecordInDb after the callback function
has been executed with an access to ActiveRecordInDb.
