Solve race xbus_populate
Fixes a crash resulting from a race between disconnecting and connecting
Astribanks (on multi-core systems)
* Use get_xbus()/put_xbus() arround xbus_populate(), so a disconnect
in the middle won't release the xbus too early.
* Aquire all XPDs before starting initialization and release them
after it finishes (so we don't have up/down races among XPDs)
