9p: reject RERROR/RLERROR with zero errcode
In p9_check_errors() (net/9p/client.c), a malicious or buggy 9p server
returning P9_RERROR or P9_RLERROR with ecode == 0 causes
p9_check_errors() to return 0 (success) while leaving the unparsed
response payload as if the expected reply message type succeeded.
Map ecode == 0 on RERROR / RLERROR to -EPROTO.
