gen8_engine_reset_prepare() can fail when HW fails to set

Let the caller of gen8_engine_reset_prepare() decide if a
failure in gen8_engine_reset_prepare is an error or not.
No complaints per se but I don't see the caller deciding and it is not
really reducing log level but converting to trace. So commit message
and patch do not align for me which I think should be improved.
I meant the return value is checked by the caller, gen8_reset_engines().
I will resend with a improved commit message.
Ah okay, maybe my bad for not figuring out that possibility. I guess it
might be passable as is, but yes, clearer commit text would be better.
Trace is good enough - we are not usually interested in seeing those as
dbg/info/notice?
