i40e/i40evf: fix error checking path

The commit 6494294f ("i40e/i40evf: Use
dma_set_mask_and_coherent") uses dma_set_mask_and_coherent() to
replace dma_set_coherent_mask() for the benefit of return error.
The conversion brings some confusion in error checking as whether
against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is
zero, the check will be against DMA_BIT_MASK(64) twice. Fix this
error checking by binding the check to the pertinent one.
