cifs: set backing_dev_info on new S_ISREG inodes



Testing on very recent kernel (2.6.36-rc6) made this warning pop:

    WARNING: at fs/fs-writeback.c:87 inode_to_bdi+0x65/0x70()
    Hardware name:
    Dirtiable inode bdi default != sb bdi cifs

...the following patch fixes it and seems to be the obviously correct
thing to do for cifs.
