Add API to wait for pending commit callbacks
This adds an API to wait for pending commit callbacks of already-synced transactions to finish processing. This is needed by the DMU-OSD in Lustre during device finalization when some callbacks may still not be called, this leads to non-zero reference count errors. See lustre.org bug 23931.
