[media] dvb-core: preserve the delivery system at cache clear
The changeset 240ab508aa is incomplete, as the first thing that happens at cache clear is to do a memset with 0 to the cache. So, the delivery system needs to be explicitly preserved there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
