The open_bdev_exclusive() function has been replaced (again) by the more generic blkdev_get_by_path() function. Additionally, the counterpart function close_bdev_exclusive() has been replaced by blkdev_put(). Because these functions are more generic versions of the functions they replaced the compatibility macro must add the FMODE_EXCL mask to ensure they are exclusive. Closes #114
