misc: genwqe: Fixes DMA mask setting
Commit 505b08777d78 ("misc: genwqe: Use dma_set_mask_and_coherent to simplify code")
changed the logic in the code.
Instead of a ||, a && should have been used to keep the code the same.
Fixes: 505b08777d78 ("misc: genwqe: Use dma_set_mask_and_coherent to simplify code")
