fcb_offset_last_n
int fcb_offset_last_n(struct fcb *fcb, uint8_t entries, uint32_t *last_n_off);
Returns the offset of n-th last element.

| Arguments | Description |
|---|---|
| fcb | Points to FCB. |
| entries | How many entries to leave. |
| last_n_off | Returned offset. |

0 on success; non-zero on failure.
