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.

meh not a fan of tihs, because it implies there is something to be done by the user here. but either it works, then the warning is just a documentation strange hardware behavior, or it does not work, which the user cannot fix himself anyway (if it's because the reset does not work) just having the warning in the task log is IMHO good enough
if $info->{has_fl_reset} && !PVE::SysFSTools::pci_dev_reset($info); }
