[IA64] simplify some condition checks in iosapic_check_gsi_range
Some condition checks on iosapic_check_gsi_range() can be omitted because always `base <= end' is assured. This patch simplifies those checks. Signed-off-by: Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
