Add proper bio_split() error handling. For any error, call raid_end_bio_io() and return.
For the case of an in the write path, we need to undo the increment in the rdev pending count and NULLify the r1_bio->bios[] pointers.
For read path failure, we need to undo rdev pending count increment from the earlier read_balance() call.

I don't think that it is proper to backport this change without bio_split() error handling update. And I don't think that it is worth backporting the bio_split() error handling update.
