PCI: xilinx-xdma: Fix error code in xilinx_pl_dma_pcie_init_irq_domain()
Currently, if the function irq_domain_add_linear() fails to allocate a new IRQ domain and returns NULL, we would then still return a success from the xilinx_pl_dma_pcie_init_irq_domain() function regardless, as the PTR_ERR(NULL) would return a value of zero. This is not a desirable outcome. Thus, fix the incorrect error code and return the -ENOMEM error code if the irq_domain_add_linear() fails to allocate a new IRQ domain.
