+
+Get the right useflag after host power off.

+Tested:
+Set a watchdog (Timer action is none and Time Use is BIOS FRB2)
+ipmitool raw 0x06 0x24 0x01 0x00 0x00 0x00 0x40 0x00
+Get watchdog
+ipmitool mc watchdog get
+Start watchdog
+ipmitool mc watchdog reset
+Get watchdog
+ipmitool mc watchdog get
+After timer is stop, set a watchdog again
+(Timer action is none and Time Use is  BIOS/POST)
+ipmitool raw 0x06 0x24 0x02 0x00 0x00 0x00 0x40 0x00
+Start watchdog and wait until timer is stop,
+Get watchdog
+ipmitool mc watchdog get
+Timer Expiration Flags should be 0x06(BIOS FRB2, BIOS/POST)
+Power down the Host
+Ipmitool chassis power off
+Check the Timer Expiration Flags(User Flags)
+ipmitool mc watchdog get
