[PATCH v4 7/9] dmaengine: dw-edma-pcie: Drop redundant pci_free_irq_vectors()

[Koichiro Den]

dw_edma_pcie enables the PCI device with pcim_enable_device(), so IRQ
vectors allocated by pci_alloc_irq_vectors() are released by
pcim_msi_release() on device release. The driver should not call
pci_free_irq_vectors() manually.

Drop the redundant remove-time cleanup and rely on the managed PCI
device lifetime instead, as documented by commit 03e4905402ae ("PCI/MSI:
Clarify pci_free_irq_vectors() usage for managed devices").
