[virt-tools-list] [PATCH 15/47] Remove unused error variables from more iterators

[Daniel P. Berrange]

The iterators used in the OsinfoDb class pass around an GError
object but none of the codepaths can ever fail, since all the
ENOMEM code was remove. The GError variable is thus redundant

* osinfo/osinfo_common.h, osinfo/osinfo_db.c: Remove GError
  from the iterators
