Call to 'pci_free_irq_vectors()' are missing both in the error handling
path of the probe function, and in the remove function. So add them.

Fixes: 64e02cb0bdfc7c ("spi: pca2xx-pci: Allow MSI")

Hi All:

I'm very sorry forgot to add change list in patch v2.

v1 -> v2:
	* modify subject name  pca2xx-pci to pxa2xx-pci.
	* add jan and Jarkko's review tag.
