vdpa: ifcvf: Use dma_set_mask_and_coherent to simplify code
'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose. While at it, fix a typo (s/confiugration/configuration) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/20201129125434.1462638-1-christophe.jaillet@wanadoo.fr Signed-off-by: Michael S.
