i2c: designware-pci: Fix BUG_ON during device removal

Function i2c_dw_pci_remove() -> pci_free_irq_vectors() ->
pci_disable_msi() -> free_msi_irqs() will throw a BUG_ON() for MSI
enabled device since the driver has not released the requested IRQ before
calling the pci_free_irq_vectors().

Here driver requests an IRQ using devm_request_irq() but automatic
release happens only after remove callback. Fix this by explicitly
freeing the IRQ before calling pci_free_irq_vectors().
