fbdev: pvr2fb: correct user pointer annotation and sentinel initializer

Browse Source 
Add __user annotation to buf, as it is passed as a user pointer in
pin_user_pages_fast(). Use an empty initializer for the sentinel
board-table entry to avoid initializing a function pointer with an
integer literal.
