fbdev: vt8500lcdfb: Fix dma_free_coherent() cpu_addr parameter

Browse Source 
Before commit 63a11adace "fbdev/vt8500lcdfb: Initialize fb_ops with
fbdev macros", the virtual address of the screen buffer was stored in
the fb_info::screen_base field and not fb_info::screen_buffer.  The
backport of commit 88b3b99243 ("fbdev: vt8500lcdfb: fix missing
dma_free_coherent()") did not take that into account.

Change the cpu_addr parameter to dma_free_coherent() accordingly.
