gdb-server: fix error reporting bugs 

GDB and OpenOCD has two different error number
spaces and no mapping exists between them.

If a specific error number is to be reported
to GDB then this has to be done at the calling
site, rather than as a generic routine that
tries to map "retval" to GDB error number speak.
