4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

commit ffdf16edfbbe77f5f5c3c87fe8d7387ecd16241b upstream

The error exit path when a duplicate is found does not kfree and cmd_entry
struct and hence there is a small memory leak.  Fix this by kfree'ing it.

Detected by CoverityScan, CID#1370198 ("Resource Leak")
