Fix two errors related to argument passing in the client interface:

Browse Source 
i) client-call-iface did not set a return value of 0 on success; hence the top stack argument was dropped as part of the status 
check causing an off-by-one error.

ii) instead of setting pb->nret to be the number of arguments returned, the (random) value being passed in was being used to 
control the number of arguments being returned.
