The code at the tail end of the loop in kvm_dirty_ring_reaper_thread()
is unreachable, because there is no way for execution to leave the
loop. Replace it with a g_assert_not_reached().

(The code has always been unreachable, right from the start
when the function was added in commit b4420f198dd8.)
