mark pstore-blk as broken

pstore-blk just pokes directly into the pagecache for the block device without going through the file operations for that by faking up it's own file operations that do not match the block device ones. As this breaks the control of the block layer of it's page cache, and even now just works by accident only the best thing is to just disable this driver.
