[zstdmt] Fix bug where extra empty blocks are emitted

When zstdmt cannot get a buffer and `ZSTD_e_end` is passed an empty
compression job can be created. Additionally, `mtctx->frameEnded` can be
set to 1, which could potentially cause problems like unterminated blocks.

The fix is to adjust to `ZSTD_e_flush` even when we can't get a buffer.
