If we resort to using the sysfs fallback mechanism we don't print
the filename. This can be deceiving given we could have a series of
callers intertwined and it'd be unclear exactly for what firmware
this was meant for.

Additionally, although we don't currently use FW_OPT_NO_WARN when
dealing with the fallback mechanism, we will soon, so just respect
its use consistently.

And even if you *don't* want to print always on failure, you may
want to print when debugging so enable dynamic debug print when
FW_OPT_NO_WARN is used.
