m68k: Add missing __user annotation in get_user()
The ptr is a pointer to userspace memory. So we need annotate it with
__user otherwise we may get sparse warnings like:
drivers/vhost/vhost.c:1603:13: sparse: sparse: incorrect type in initializer (different address spaces) @@ expected void const *__gu_ptr @@ got unsigned int [noderef] [usertypvoid const *__gu_ptr @@
