btrfs: raid56: avoid double for loop inside __raid56_parity_recover()

Browse source

The double for loop can be easily converted to single for loop as we're
really iterating the sectors in their bytenr order.

The only exception is the full stripe skip, however that can also easily
be done inside the loop.  Add an ASSERT() along with a comment for that
specific case.
