Revert "exofs: Set i_mapping->backing_dev_info anyway"
This reverts commit 115e19c53501edc11f730191f7f047736815ae3d. Apparently setting inode->bdi to one's own sb->s_bdi stops VFS from sending *read-aheads*. This problem was bisected to this commit. A revert fixes it. I'll investigate farther why is this happening for the next Kernel, but for now a revert. I'm sending to stable@kernel.org as well, since it exists also in 2.6.37. 2.6.36 is good and does not have this patch.
