kernel: misc: pci_endpoint_test: Free IRQs before removing the device

A use-after-free flaw was found in the Linux kernel's PCI endpoint test driver. In pciendpointtestremove, IRQs are freed after the device is removed, creating a race window where an IRQ can be delivered after device memory is freed. The IRQ handler then accesses invalid memory, causing a kernel...
