bcache: fixup init dirty data errors

bcache: fixup init dirty data errors

We found that after long run, the dirty_data of the bcache device
will have errors. This error cannot be eliminated unless re-register.

We also found that reattach after detach, this error can accumulate.

In bch_sectors_dirty_init(), all inode <= d->id keys will be recounted
again. This is wrong, we only need to count the keys of the current
device.
