md/raid5: fix miscalculation of 'end_sector' in raid5_read_one_chunk()

Browse source

commit 8557dc2712 upstream.

'end_sector' is compared to 'rdev->recovery_offset', which is offset to
rdev, however, commit e82ed3a4fb ("md/raid6: refactor
raid5_read_one_chunk") changes the calculation of 'end_sector' to offset
to the array. Fix this miscalculation.
