Use correct define for the name array size. The change breaks ABI and
hence cannot be backported to stable branches.

Fixes: 38c9817ee1d8 ("mempool: adjust name size in related data types")

This patch has a CI failure in DTS in test_scatter_mbuf_2048 for Fortville_Spirit NIC. I am not sure how this change is related to the failure. The log is as follows:

TestScatter: Test Case test_scatter_mbuf_2048 Result FAILED: 'packet receive error'

Has anyone seen this error? Is this a known issue?

Thanks,
Honnappa

I saw a lot of patches failed on test_scatter_mbuf_2048, the case could be passed in intel lab.

This is maintained by UNL guys.
