misc: pci_endpoint_test: Re-init completion for every test
The irq_raised completion used to detect the end of a test case is
initialized when the test device is probed, but never reinitialized again
before a test case. As a result, the irq_raised completion synchronization
is effective only for the first ioctl test case executed. Any subsequent
call to wait_for_completion() by another ioctl() call will immediately
return, potentially too early, leading to false positive failures.
Fix this by reinitializing the irq_raised completion before starting a new
ioctl() test command.
