idpf: only assign num refillqs if allocation was successful

As reported by AI review [1], if the refillqs allocation fails, refillqs
will be NULL but num_refillqs will be non-zero. The release function
will then dereference refillqs since it thinks the refillqs are present,
resulting in a NULL ptr dereference.

Only assign the num refillqs if the allocation was successful. This will
prevent the release function from entering the loop and accessing
refillqs.
