Memory leak in ldns_dnssec_zone_new_frm_fp_l()

[FGasper]

#186 adds memory-leak detection to the CI run, and it indicates a memory leak in this function.

What appears to be happening is that this duplicated record in 25-ZONEMD:

duplicate.example.	300	IN	TXT	"I must be digested just once"

… is represented by 2 rr structs, only 1 of which gets assigned to the dnssec_zone. The other is never freed.

Will this be fixed soon?

[FGasper]

@Zero3K I think any fix would have to be pretty invasive. I could be wrong though.
