md: raid1: Fix restoration of bio between failed read and write.
When performing a "recovery" or "check" pass on a RAID1 array, we read
from each device and possible, if there is a difference or a read error,
write back to some devices.
We use the same 'bio' for both read and write, resetting various fields
between the two operations.
We forgot to reset bv_offset and bv_len however. These are often left
unchanged, but in the case where there is an IO error one or two sectors
into a page, they are changed.
This results in correctable errors not being corrected properly. It does
not result in any data corruption.
