[IA64] Don't alloc empty frame in ia64_switch_mode_phys
I think ia64_switch_mode_phys and ia64_switch_mode_virt does not need to alloc an empty frame. An empty frame is required by loadrs but flushrs does not need that. Signed-off-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
