In order for Unmap() to be callable from ExitBootServices() event handler context (for cleaning up a BusMasterCommonBuffer[64] operation), we have to completely liberate the affected path in Unmap() from dynamic memory management. The last remaining piece is the release of the MAP_INFO structure. Rather than freeing it with FreePool(), recycle it to an internal list. Elements of this "free list" can be reused for any kind of Map() operation, and can be freed later, or recycled again.
