Use the new function pcim_alloc_irq_vectors() to allocate IRQ vectors, the pcim_alloc_irq_vectors() function, an explicit device-managed version of pci_alloc_irq_vectors(). If pcim_enable_device() has been called before, then pci_alloc_irq_vectors() is actually a device-managed function. It is used here as a device-managed function, So replace it with pcim_alloc_irq_vectors(). At the same time, Remove the pci_free_irq_vectors() function to simplify the error handling path. the freeing resources will take automatically when device is gone.
