blkfront: Lock blkfront_info when closing ...
The bdev .open/.release fops race against backend switches to Closing,
handled by the XenBus thread.
The original code attempted to serialize block device holders and
xenbus only via bd_mutex. This is insufficient, the info->bd pointer
may already be stale (or null) while xenbus tries to bump up the
refcount.
Protect blkfront_info with a dedicated mutex.
