'end_sector' is compared to 'rdev->recovery_offset', which is offset to
rdev, however, commit e82ed3a4fbb5 ("md/raid6: refactor
raid5_read_one_chunk") changes the calculation of 'end_sector' to offset
to the array. Fix this miscalculation.

Fixes: e82ed3a4fbb5 ("md/raid6: refactor raid5_read_one_chunk")

This needs a stable tag as well, Fixes alone is not enough to guarantee
it ends up in stable.

Song, are you picking this up?

Yes, I will test it and send it via md-fixes.

Thanks,
Song
