sidedatacopies: fast path data fetching if revision has no sidedata
When using the side data mode, we know their won't be any copy information
sidedata. Skipping revision restoration give an important speed boost.
In the future, there will be other user of sidedata, reducing the efficiency of
this. We should consider adding a dedicated flag in revlog V2 to preserve this
optimisation. The current situation is good enough for now.
