[PATCH v3] PCI: dwc: Fix potential truncation in dw_pcie_edma_irq_verify()

[Niklas Cassel <cassel@kernel.org>]

Increase the size of the string buffer to avoid potential truncation in
dw_pcie_edma_irq_verify().

This fixes the following build warning when compiling with W=1:

drivers/pci/controller/dwc/pcie-designware.c: In function ‘dw_pcie_edma_detect’:
drivers/pci/controller/dwc/pcie-designware.c:989:50: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 3 [-Wformat-truncation=]
  989 |                 snprintf(name, sizeof(name), "dma%d", pci->edma.nr_irqs);
      |                                                  ^~

Changes since v2:
-Simply increase the size of the string buffer instead of chaning the
 print format specifier.
