net/mlx5: Increase size of irq name buffer

Without increased buffer size, will trigger -Wformat-truncation with W=1
for the snprintf operation writing to the buffer.

    drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c: In function 'mlx5_irq_alloc':
    drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c:296:7: error: '@pci:' directive output may be truncated writing 5 bytes into a region of size between 1 and 32 [-Werror=format-truncation=]
      296 |    "%s@pci:%s", name, pci_name(dev->pdev));
          |       ^~~~~
    drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c:295:2: note: 'snprintf' output 6 or more bytes (assuming 37) into a destination of size 32
      295 |  snprintf(irq->name, MLX5_MAX_IRQ_NAME,
          |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      296 |    "%s@pci:%s", name, pci_name(dev->pdev));
          |    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
