Unlike the kernel macros, our __get_user() and __put_user() do not
return a failure code. Kernel code typically has a style of
err |= __get_user(...); err |= __get_user(...);
and then checking err at the end. In sparc64_get_context() our
version of the code dropped the accumulating into err but left the
"if (err) goto do_sigsegv" checks, which will never be taken. Delete
unnecessary if()s.
