hurd: Fix sigreturn clobbering some xmm registers

__sigreturn2 uses _hurd_sigstate_unlock after restoring the interrupted
xmm values, we thus need it not to touch xmm. It makes sense to inline
sigstate_is_global_rcv _hurd_sigstate_lock/unlock anyway. unlock calls
gsync_wake, so we need to avoid xmm there as well.
