[PATCH v3 3/4] i2c: designware: Use the correct name of device-managed function

[Dejin Zheng <zhengdejin5@xxxxxxxxx>]

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, simplify the error
handling path.
