btrfs: calculate physical_end using dev_extent_len directly in scrub_stripe()
The variable @physical_end is the exclusive stripe end, currently it's
calculated using @physical + @dev_extent_len / map->stripe_len *
map->stripe_len.
And since at allocation time we ensured dev_extent_len is stripe_len
aligned, the result is the same as @physical + @dev_extent_len.
So this patch will just assign @physical and @physical_end early,
without using @nstripes.
This is especially helpful for any possible out: label user, as now we
only need to initialize @offset before going to out: label.
Since we're here, also make @physical_end constant.
