PCI: xilinx-xdma: Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
The error paths that follow calls to the devm_request_irq() functions
within the xilinx_pl_dma_pcie_setup_irq() reference an uninitialized
symbol each that also so happens to be incorrect.
Thus, fix this omission and reference the correct variable when invoking
a given dev_err() function following an error.
This problem was found using smatch via the 0-DAY CI Kernel Test service:
drivers/pci/controller/pcie-xilinx-dma-pl.c:638 xilinx_pl_dma_pcie_setup_irq() error: uninitialized symbol 'irq'.
drivers/pci/controller/pcie-xilinx-dma-pl.c:645 xilinx_pl_dma_pcie_setup_irq() error: uninitialized symbol 'irq'.
Fixes: 8d786149d78c ("PCI: xilinx-xdma: Add Xilinx XDMA Root Port driver")
