I am not sure if this tells you about the blocks that have been marked as deleted but you can look at the free_blocks member in the spiffs_t struct. (There is a delete blocks count too but you could dump all three and that should give you a good idea of what is going on with the flash).

  typedef struct spiffs_t { 
  ....
     // current number of free blocks
     u32_t free_blocks;
     // current number of busy pages
     u32_t stats_p_allocated;
     // current number of deleted pages
     u32_t stats_p_deleted;
