Subject: [PATCH v2 1/2] net: thunderx: Fix issue with IRQ namimg

From: Sunil Goutham <sgoutham@...ium.com>

This patch fixes a regression caused by previous commit
when irq name exceeds 20 byte array if interface's name
size is large.

Fixes: e412621394fa ("net: thunderx: Use netdev's name for naming VF's interrupts")
