[OpenBIOS] [PATCH 1/2] CIF: Emit debug linebreak when method fails

[Andreas Färber]

When DEBUG_CIF is defined, a serial message of the form "method(...) = "
is emitted by dump_service(). After successful execution the return value
and a linebreak are emitted by dump_return(). If however the method fails,
nothing is emitted, so that subsequent method calls end up in place of the
return value. Observed for getproplen with AIX.

Emit an error indication and a linebreak when DEBUG_CIF is defined.
