block/sed-opal: allocate struct opal_dev dynamically
Insted of bloating the containing structure with it all the time this
allocates struct opal_dev dynamically. Additionally this allows moving
the definition of struct opal_dev into sed-opal.c. For this a new
private data field is added to it that is passed to the send/receive
callback. After that a lot of internals can be made private as well.
