fix a message parsing regression

the fix for CVE-2023-4408 introduced a regression in the message
parser, which could cause a crash if duplicate rdatasets were found
in the question section. this commit ensures that rdatasets are
correctly disassociated and freed when this occurs.

(cherry picked from commit 4c19d35614f8cd80d8748156a5bad361e19abc28)
