Subject: [PATCH] crypto: qat - 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, also remove some unless extra () in the 32 bits case.
Signed-off-by: Christophe JAILLET <christophe.jaillet@...adoo.fr>

Instead of returning -EFAULT, we could also propagate the error returned
by dma_set_mask_and_coherent()
