Revert "exofs: Set i_mapping->backing_dev_info anyway"

commit 0b0abeaf3d30cec03ac6497fe978b8f7edecc5ae upstream.

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.
