Summary
net: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback
Details

In the Linux kernel, the following vulnerability has been resolved:

net: octeonepvf: fix freeirq devid mismatch in IRQ rollback

octepvfrequestirqs() requests MSI-X queue IRQs with devid set to ioqvector. If requestirq() fails part-way, the rollback loop calls freeirq() with devid set to 'oct', which does not match the original dev_id and may leave the irqaction registered.

This can keep IRQ handlers alive while ioq_vector is later freed during unwind/teardown, leading to a use-after-free or crash when an interrupt fires.

Fix the error path to free IRQs with the same ioqvector devid used during request_irq().
