Jan Kara ca67881dce init: Initialize noop_backing_dev_info early 
[ Upstream commit 4bca7e80b6 ]

noop_backing_dev_info is used by superblocks of various
pseudofilesystems such as kdevtmpfs. After commit 10e1407310
("writeback: Fix inode->i_io_list not be protected by inode->i_lock
error") this broke because __mark_inode_dirty() started to access more
fields from noop_backing_dev_info and this led to crashes inside
locked_inode_to_wb_and_lock_list() called from __mark_inode_dirty().
Fix the problem by initializing noop_backing_dev_info before the
filesystems get mounted.

Fixes: 10e1407310 ("writeback: Fix inode->i_io_list not be protected by inode->i_lock error")
