potential memory leak on config failure

[magenbluten]

the region created here:

unbound/services/rpz.c

Line 388 in 52b0480

r->region = regional_create_custom(sizeof(struct regional));

does not get free'd in the err handling path:

unbound/services/rpz.c

Line 435 in 52b0480

err:

assuming the region could be created but one of the following actions fails.

Thanks for the review! That is a good fix, committed in a87f05b for the next release.
