For this case, we shouldn't set pcierr_recovery to true wrongly, which blocks the driver to release the allocated interrupts and their handlers. Eventually, we can't disable MSI or MSIx successfully because of the MSI or MSIx interrupts still have associated interrupt actions, which is turned into following stack dump.
