Subject: [PATCH net-next,1/9] octeontx2-af: Fix interrupt name strings completely

From: Dave Kleikamp <dave.kleikamp@...cle.com>

The earlier commit: ("octeontx2-af: Fix interrupt name strings") fixed
one instance of a stack address being saved as if it were static.
This patch fixes another instance.
