ENGR00314119 [#1183] fixed database mutex multi-lock issue
The abnormal flow with the monkey test freeze problem is as below:
gckKERNEL_DestroyProcessDB--> aquire mutex --> gckCOMMAND_Detach(gckEVENT_FreeContiguousMemory) -->
___RemoveRecordFromProcessDB --> gckKERNEL_RemoveProcessDB --> aquire the same mutex
the fix is to disable mutex lock when perform record destory operations
