SST files were not sync'ed to disk by default. Machine crash may happen before the explicit sync (which happens at DB close), leading to an inconsistent state and badger not able to open.
It is better to explicitly do a sync. This PR explicitly Msync the SST and removes the table options SyncWrites.

This PR adds debug information for the crash in `initIndex`. We suspect that it may be due to unsynced mmap (#1625), or because of mishandling of SST files.
