[PATCH 11/12] golang/xenlight: do not negate ret when converting to Error



There are several locations where the return code from calling into C is
negated when being converted to Error. This results in error strings
like "libxl error: <x>", rather than the correct message. Fix all
occurrances of this by running:

  gofmt -w -r 'Error(-ret) -> Error(ret)' xenlight.go

from tools/golang/xenlight.
