firewire: ohci: prevent leak of left-over IRQ on unbind
In the Linux kernel, the following vulnerability has been resolved:
firewire: ohci: prevent leak of left-over IRQ on unbind
Commit 5a95f1ded28691e6 ("firewire: ohci: use devres for requested IRQ")
also removed the call to free_irq() in pci_remove(), leading to a
leftover irq of devm_request_irq() at pci_disable_msi() in pci_remove()
when unbinding the driver from the device
remove_proc_entry: removing non-empty directory 'irq/136', leaking at
least 'firewire_ohci'

also remove it in fail_msi: of pci_probe() as this would lead to
