upcall: set upcall.status on parse failure

Browse source 
when open parsing fails, we were still returning upcall.status==NO_ERROR, so the driver assumed the open succeeded.  other operations then sent up an open_state==NULL, and crashed the daemon.  when upcall_parse() returns an error, set upcall.status to notify the driver

upcall_parse() prints a 'parsing of upcall <name> failed with <error>.' message on failure, so i removed redundant messages from the individual upcall parsing functions
