[PATCH 1/2] xen-9pfs: Fix log messages of reply errors

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

If delivery of some 9pfs response fails for some reason, log the
error message by mentioning the 9P protocol reply type, not by
client's request type. The latter could be misleading that the
error occurred already when handling the request input.
