[IA64] remove redundant local_irq_save() calls from sn_sal.h
sn_change_memprotect() does a local_irq_save() then calls ia64_sal_oemcall_nolock() which calls SAL_CALL_NOLOCK() which also does a local_irq_save(). This patch removes the redundant local_irq_save() and local_irq_restore() calls in sn_change_memprotect() and sn_inject_error().
