ublk: clear auto buf reg before updating io->buf in batch commit

Browse source

ublk_batch_commit_io() stored the new auto_buf into io->buf before
calling ublk_clear_auto_buf_reg(). Clear takes the unregister index
from io->buf.auto_reg, so it could drop the new slot and leave the
old registered buffer behind.
