Fixes the following sparse errors in drivers/md/raid10.c error:
incompatible types in comparison expression (different address spaces).

The error was because of the following line in function read_balance():

rdev = rcu_dereference(conf->mirrors[disk].replacement);
    if (rdev == NULL || test_bit(Faulty, &rdev->flags) ||
        r10_bio->devs[slot].addr + sectors > rdev->recovery_offset)
    rdev = rcu_dereference(conf->mirrors[disk].rdev);

Annotating the struct md_rdev *rdev and *replacement in
drivers/md/raid10.h with __rcu fixes the sparse error.
