Hi.

Here are couple of bugfixes for blkfront.

 1. Bdev removal was slightly buggy. [Is nobody out there using
    block-detach??] Also it seems like we'be been leaking the gendisk
    structs for a long time.

 2. Fixes most common occasions where disk open/close races against
    backend state switches. This one didn't come for free:
        * xenbus_switch_state growing transactions again.
        * New mutex in blkfront_info
        * Bdev .open/.close rewritten accordingly.

Cheers,
Daniel
