[PATCH -next] dmaengine: idxd: fix PCI_MSI build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build errors when CONFIG_PCI_MSI is not enabled by making the
driver depend on PCI_MSI:

ld: drivers/dma/idxd/device.o: in function `idxd_mask_msix_vector':
device.c:(.text+0x26f): undefined reference to `pci_msi_mask_irq'
ld: drivers/dma/idxd/device.o: in function `idxd_unmask_msix_vector':
device.c:(.text+0x2af): undefined reference to `pci_msi_unmask_irq'

Vinod, I submitted this fix patch last week:
https://patchwork.kernel.org/patch/11649231/

But I think maybe Randy's patch may be more preferable? You can apply this one 
and ignore my submission.
