Qu Wenruo a9ad4d87aa btrfs: raid56: make error_bitmap update atomic 
In the rework of raid56 code, there is very limited concurrency in the
endio context.

Most of the work is done inside the sectors arrays, which different bios
will never touch the same sector.

But there is a concurrency here for error_bitmap. Both read and write
endio functions need to touch them, and we can have multiple write bios
touching the same error bitmap if they all hit some errors.

Here we fix the unprotected bitmap operation by going set_bit() in a
loop.

Since we have a very small ceiling of the sectors (at most 16 sectors),
such set_bit() in a loop should be very acceptable.

Fixes: 2942a50dea74 ("btrfs: raid56: introduce btrfs_raid_bio::error_bitmap")
