Michael Marley 61927b9f11 manager: Fix HW watchdog when systemd starts before driver loaded 
When manager_{set|override}_watchdog is called, set the watchdog timeout
regardless of whether the hardware watchdog was successfully initialized.  If
the watchdog was requested but could not be initialized, then instead of
pinging it, attempt to initialize it again.  This ensures that the hardware
watchdog is initialized even if the kernel module for it isn't loaded when
systemd starts (which is quite likely, unless it is compiled in).

This builds on work by @danc86 in https://github.com/systemd/systemd/pull/17460,
but fixes the issue of not updating the watchdog timeout with the actual value
from the hardware.

Fixes https://github.com/systemd/systemd/issues/17838
