wdctl: Workaround reported boot-status bits not being present in wd->…
…ident.options Some watchdog drivers are capable of reporting WDIOF_CARDRESET in their bootstatus, but they do not advertise this in the options field returned by the WDIOC_GETSUPPORT ioctl. This causes wdctl to not print the CARDRESET flag on these devices, even when the reset was caused by the watchdog and this is being reported in the WDIOC_GETBOOTSTATUS return. Add a workaround by or-ing any bits which are set in the status and bstatus returns into wd->ident.options so that reported flags will get printend independent of them being advertised as supported in wd->ident.options. This will make wdctl print a CARDRESET line when the system was actually reset by the watchdog while omitting it when it was not reset by the watchdog. At least on drivers which have the CARDRESET is missing from info.options problem. On other drivers the CARDRESET line will always be printend, but the actual reported value will change.
