Jianglei Nie ddf75a86ab auxdisplay: hd44780: Fix potential memory leak in hd44780_remove() 
hd44780_probe() allocates a memory chunk for hd with kzalloc() and
makes "lcd->drvdata->hd44780" point to it. When we call hd44780_remove(),
we should release all relevant memory and resource. But "lcd->drvdata
->hd44780" is not released, which will lead to a memory leak.

We should release the "lcd->drvdata->hd44780" in hd44780_remove() to fix
the memory leak bug.

Fixes: 718e05ed92 ("auxdisplay: Introduce hd44780_common.[ch]")
