net/mlx5: offset comp irq index in name by one

The mlx5 comp irq name scheme is changed a little bit between
commit 3663ad34 ("net/mlx5: Shift control IRQ to the last index")
and commit 3354822c ("net/mlx5: Use dynamic msix vectors allocation").
The index in the comp irq name used to start from 0 but now it starts
from 1. There is nothing critical here, but it's harmless to change
back to the old behavior, a.k.a starting from 0.

Fixes: 3354822c ("net/mlx5: Use dynamic msix vectors allocation")
