patch 'net/cnxk: fix possible null dereference in telemetry' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c5693310a68473007a05801a279684e636ff1cb8

Thanks.

Kevin

[ upstream commit 67ead3fa8c3a6775b2b0c9888afd08bdf02c4d9b ]

The return value of rte_tel_data_alloc() may be null pointer.
Add missing check vs null.
