erofs-utils: no compression case for tail-end block in vle_write_indexes()

Note that count value will be always greater than EROFS_BLKSIZ when
calling erofs_compress_destsize() in vle_compress_one(). So, the d1
always >= 1 for compressed block in vle_write_indexes(). That is to
say tail-end block can't be compressed.
