The dump of dynamic fields and flags fails if the shm is already
allocated. Add a check to fix the issue.

Hi Alexander,
Sorry for late feedback, I forgot to reply to your v2.
I'm resending your fix with the 2 patches merged together, so it
can be included in 21.11.
Thanks,
Olivier
v3:
* Merge the 2 patches from v2 and add a commit log
v2:
* Drop changes with log message from v1, because rte_errno is not always set
