bcache: fixup init dirty data errors

Browse Source 
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.

Fixes: b144e45fc5 ("bcache: make bch_sectors_dirty_init() to be multithreaded")
