Qu Wenruo 3692004465 btrfs: raid56: avoid double for loop inside finish_rmw()
We can easily calculate the stripe number and sector number inside the
stripe.  Thus there is not much need for a double for loop.

For the only case we want to skip the whole stripe, we can manually
increase @total_sector_nr.
This is not a recommended behavior, thus every time the iterator gets
modified there will be a comment along with an ASSERT() for it.
