md/raid1: restrict atomic write limits and handle runtime constraints
Restrict the RAID1 atomic write limits by setting chunk_sectors to
BARRIER_UNIT_SECTOR_SIZE so that atomic writes never straddle a barrier
unit.
A bio that passes block-layer validation may still become unserviceable
within RAID1 due to bad blocks or write-behind constraints. In the former
case, complete the bio with EIO. In the latter case, disable
write-behind rather than failing the bio with EIO.
Fixes: f2a38abf5f1c ("md/raid1: Atomic write support")
Fixes: a4c55c902670 ("md/raid1: simplify raid1_write_request() error handling")
