[VOL-1385] Remove parent's device flows after child deletion

This commit fixes the following:

1) Do not automatically raise an error when no routes can be
found when decomposing a flow.  In some cases flows can still
be decomposed (e.g. some trap flows).
2) Delete flows from a parent device when receiving delete flow
instructions from the OF controller after a child device has
been deleted (previously was failing as no route could be
obtained).
