Commit d4c7d1a089d6 ("PCI: dwc: dra7xx: Push request_irq() call to the bottom of probe") moved the IRQ request for "dra7xx-pcie-main" towards the end of dra7xx_pcie_probe(). However, the error handling does not take into account the initialization performed by either dra7xx_add_pcie_port() or dra7xx_add_pcie_ep(), depending on the mode of operation. Fix the error handling to address this.
