zoran: don't bother with struct file * in zoran_map
all we need it for is file->private_data, which is assign-once, already assigned by that point and, incidentally, its value is already in use by zoran ->mmap() anyway. So just store that pointer instead... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
