frv: fix address verification holes in setup_frame/setup_rt_frame
a) sa_handler might be maliciously set to point to kernel memory;
blindly dereferencing it in FDPIC case is a Bad Idea(tm).
b) I'm not sure you need that set_fs(USER_DS) there at all, but if you
do, you'd better do it *before* checking the frame you've decided to
use with access_ok(), lest sigaltstack() becomes a convenient
roothole.
