[PATCH] PCI/docs: Fix references to DMA set mask function

[Alex Williamson <alex.williamson@redhat.com>]

The function is dma_set_mask(), fix a missed instance of the old
pci_set_dma_mask() and a reference to a function that doesn't exist.

Fixes: 05b0ebd06ae6 ("PCI/doc: cleanup references to the legacy PCI DMA API")
