Delete secure stops by key set ID.

Browse Source 
[ Merge of http://go/wvgerrit/165617 ]

Similar to the issue with updating secure stops by PST (see
http://go/wvgerrit/165597), when deleting different secure stops with
the same PST results in unintended behavior.  This CL changes how the
CDM identifies which secure stop to delete from storaged based on the
key set ID rather than the PST.
