PCI: xilinx-cpm: Fix IRQ domain leak in error path of probe
[ Upstream commit 57b0302240741e73fe51f88404b3866e0d2933ad ]
The IRQ domain allocated for the PCIe controller is not freed if
resource_list_first_type() returns NULL, leading to a resource leak.
This fix ensures properly cleaning up the allocated IRQ domain in
the error path.
