[PATCH 03/12] dump: Assert cpu_get_note_size() can't fail

[Markus Armbruster <armbru@redhat.com>]

The only way cpu_get_note_size() can return a negative value is
integer overflow in the non-stub versions, which is a programming
error.  The stub version is not actually reachable, because the
cpu_get_dump_info() stub will fail first.  Use assert().  This gets
rid of another use of QERR_UNSUPPORTED.
