ipmi/sim: fix watchdog_expired data type error in IPMIBmcSim struct

Browse Source 
1) watchdog_expired is set bool which value could only be 0 or 1,
but watchdog_expired every bit mean different Timer Use.

2) Use the command  -ipmitool mc get watchdog-  to query
ipmi-watchdog status in guest.
...
[root@localhost ~]# ipmitool mc watchdog get
Watchdog Timer Use:     SMS/OS (0x44)
Watchdog Timer Is:      Started/Running
Watchdog Timer Actions: Hard Reset (0x01)
Pre-timeout interval:   0 seconds
Timer Expiration Flags: 0x00
Initial Countdown:      60 sec
Present Countdown:      57 sec
...
bool for watchdog_expired results -Timer Expiration Flags- always
be 0x00 or 0x01, but the -Timer Expiration Flags- indicts the Timer Use
after timeout. So change watchdog_expired data type from bool to uint8_t
to fix this problem.

[I checked, a bool and uint8 are the same size for the vmstate transfer,
 so this should be fine.]
