[WATCHDOG] iTCO_wdt: fix memory corruption when RCBA is disabled by hardware



According to 9.1.33 on p.343 of ICH8.pdf RCBA can be disabled by
hardware if bit 0 of RCBA register is not set.

Perform correct check for this to prevent memory corruption under
some virtual machines where this feature is disabled.
