nfp: make use of the DMA_ATTR_SKIP_CPU_SYNC attr
DMA unmap may destroy changes CPU made to the buffer. To make XDP
run correctly on non-x86 platforms we should use the
DMA_ATTR_SKIP_CPU_SYNC attribute.
Thanks to using the attribute we can now push the sync operation to the
common code path from XDP handler.
A little bit of variable name reshuffling is required to bring the
code back to readable state.
