Revert "net: stmmac: set PP_FLAG_DMA_SYNC_DEV only if XDP is enabled"

Browse Source 
This reverts commit b514c47ebf.

The commit describes that we don't have to sync the page when
recycling, and it tries to optimize that case. But we do need
to sync after allocation. Recycling side should be changed to
pass the right sync size instead.
