sh: Fix up thread info pointer in syscall_badsys resume path.
Entry to resume_userspace expects r8 to contain current_thread_info, which happens in all paths except for syscall_badsys, where r8 was being inadvertently trampled. Reload it before the branch. Signed-off-by: Hideo Saito <saito@densan.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
