stable inclusion from linux-4.19.207 commit 161818ff30e696c3eec58a7617d38c9fd5889296
--------------------------------
[ Upstream commit 761608f5cf70e8876c2f0e39ca54b516bdcb7c12 ]
In the for loop all nfeth_dev array members should be freed, not only the first one. Freeing only the first array member can cause double-free bugs and memory leaks.
