  • [buffermgr] Moved switch statement outside of if-statmement in Buffermgr::doTask

The switch statement which would normally erase buffer events was moved to be inside the if-statement which would only enter if the event is a SET event. This was introduced in commit e5329c39.

This would cause an infinite loop, since non-set events would never be erased.

The switch statement has now been moved to occur outside the if, allowing for non-set commands to be processed.

**What I did**

Fix the Mem Leak by moving the raw pointers in type_maps to use smart pointers

**Why I did it**
