PCI: endpoint: pci-epf-test: Don't free doorbell IRQ unless requested

Browse source

pci_epf_test_doorbell_cleanup() unconditionally calls free_irq() for the
doorbell virq, which can trigger "Trying to free already-free IRQ"
warnings when the IRQ was never requested or when request_threaded_irq()
failed.

Move free_irq() out of pci_epf_test_doorbell_cleanup() and invoke it
only after a successful request, so that free_irq() is not called for
an unrequested IRQ.
