Since pve-common commit:
eff5957 (sysfstools: file_write: properly catch errors)
this check here fails now when the reset does not work. It turns out
that resetting the device is not always necessary, and we previously
ignored most errors when trying to do so.
To restore that functionality, downgrade this `die` to a warning.
If the device really needs a reset to work, it will either fail later
during startup, or not work correctly in the guest, but that behavior
existed before and is AFAIK not really detectable from our side.
Also improve the warning message a bit to not scare users and explain
that we're continuing.
