nilfs2: fix NULL pointer dereference at nilfs_bmap_lookup_at_level()
If the i_mode field in inode of metadata files is corrupted on disk, it
can cause the initialization of bmap structure, which should have been
called from nilfs_read_inode_common(), not to be called. This causes a
lockdep warning followed by a NULL pointer dereference at
nilfs_bmap_lookup_at_level().
This patch fixes these issues by adding a missing sanitiy check for the
i_mode field of metadata file's inode.
