SystemError: error return without exception set
In the python bindings, returning NULL makes python think an
exception was thrown, while returning the None object lets the
wrappers know that a libvirt error exists.
Reported by Nox DaFox, fix suggested by Dan Berrange.
* python/libvirt-override.c (libvirt_virDomainBlockPeek)
(libvirt_virDomainMemoryPeek): Return python's None object, so
wrapper knows to check libvirt error.
