This patch fixes segfault encountered during dev_uninit/close routine.
KNI sample app can be used to reproduce the issue.
backported from upstream commit 316e412

Hi Ajit,
Thanks for the backport. Few minor comments though:
- the dev mailing list should not be cc'ed (thus I removed it).
- the commit log should not be changed, except an extra line is needed:
[ backported from upstream commit 316e412299fde9f8f099ef957aa04dc6c43d02a2 ]
You could either send another veresion, or I will handle it (copy &
paste the original commit log) for you while apply.
Thanks.

I had cloned the dpdk-stable for the first time. So it did not have the
usual git hooks.
By the time I got the email about the checkpatch failure, it was late
anyway.

If it isn't much, could you just use this version and do the copy-paste
this time.
Otherwise I will send something out tomorrow. My laptop battery is almost
out of power.
