Per cxl spec r3.1, for multiple dynamic capacity event records grouped via
the More flag, the last record in the sequence should clear the More flag.

Before the change, the More flag of the event record is cleared before
the loop of inserting records into the event log, which will leave the flag
always set once it is set in the loop.
