mm/memory: slightly simplify copy_present_pte()
Let's move the pinning check into the caller, to simplify return code
logic and prepare for further changes: relocating the
page_needs_cow_for_dma() into rmap handling code.
While at it, remove the unused pte parameter and simplify the comments a
bit.
No functional change intended.
