media: vb2: unify calling of set_page_dirty_lock
Currently videobuf2-dma-sg checks for dma direction for
every single page and videobuf2-dc lacks any dma direction
checks and calls set_page_dirty_lock unconditionally.
Thus unify and align the invocations of set_page_dirty_lock
for videobuf2-dc, videobuf2-sg memory allocators with
videobuf2-vmalloc, i.e. the pattern used in vmalloc has been
copied to dc and dma-sg.
