If the default dev args 'proto_xtr' is not in the first position, it
will overwrite the parsed queue map value, so use an new variable to
save the default.

And enhance the error message printing to show the right information.

These two lines seems irrelevant to this patch, I noticed that the resource
free operation was contained in the original patch, and they are removed 
unexpectedly by commit bd513ece3c40 ("net/ice: release port upon close"), 
sorry for not catching it when reviewing.

Prefer one individual patch for the fix.

Thanks,
Xiaolong

Planed to send two patches, but a little lazy. :) Will do this in v2.
