libdmabufheap: Do not keep track of CPU Sync type for DMA-BUF fds.
Since the library does not have a way to track whether the fd has been
closed, the synctype data cached by it can get stale. It is also
incorrect to assume that the same BufferAllocator instance would be used
for CpuSyncStart() and CpuSyncEnd()(for instance, the fd maybe passed
over binder to another process after a CpuSyncStart() invocation).
