mtd: mtdchar: Do not corrupt backing device of device node inode
We cannot modify file->f_mapping->backing_dev_info, because it will corrupt
backing device of device node inode, since file->f_mapping is equal to
inode->i_mapping (see __dentry_open() in fs/open.c).
Let's introduce separate inode for MTD device with appropriate backing
device.
[dwmw2: Refactor to keep it all entirely within mtdchar.c; use iget_locked()]
