mtd: fix bdev exclusive open bugs in block2mtd::add_device()
There are two bdev exclusive open bugs.
* open_bdev_exclusive() must not be called with NULL holder. Use dev
as the holder.
* open_by_devnum() doesn't open the bdev exclusively but
block2mtd_free_device() always assumes it. Explicitly claim the
bdev.
The latter is rather clumsy but will be simplified with future
blkdev_get/put() cleanups.
- Updated to use local variable @mode to cache FMODE_* masks as
suggested by Artem Bityutskiy.
