writeback: fix false warning in inode_to_wb()
commit 9e888998ea4d22257b07ce911576509486fa0667 upstream.
inode_to_wb() is used also for filesystems that don't support cgroup
writeback. For these filesystems inode->i_wb is stable during the
lifetime of the inode (it points to bdi->wb) and there's no need to hold
locks protecting the inode->i_wb dereference. Improve the warning in
inode_to_wb() to not trigger for these filesystems.
