ethernet: s2io: Use dma_set_mask_and_coherent() and simplify code
Use dma_set_mask_and_coherent() instead of unrolling it with some
dma_set_mask()+dma_set_coherent_mask().
Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never
fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
That said, 'dma_flag' can only be 'true' after a successful
dma_set_mask_and_coherent().
Simplify code and remove some dead code accordingly, including the now
useless 'high_dma_flag' field in 'struct s2io_nic'.
