The patch fixes flush cache issue in
CreateSecondLevelPagingEntryTable().
We found some video cards still not work even they have
been added to the exception list.
In CreateSecondLevelPagingEntryTable(), the check
"(BaseAddress >= MemoryLimit)" may be TRUE and "goto Done"
will be executed, then the FlushPageTableMemory operations
at the end of the function will be skipped.
Instead of "goto Done", this patch uses "break" to break
the for loops, then the FlushPageTableMemory operations
at the end of the function could have opportunity to be
executed.
The patch also fixes a miscalculation for Lvl3End.
