Avoid realloc in bulk execution

    Description

      _mongoc_write_command splits a stream of documents (all inserts, all updates, or all deletes) to the server 16 mb at a time. Between each 16 mb batch it destroys the command document cmd and reinitializes it. This wastes time in malloc. Just bson_reinit it after the first batch, and bson_destroy only at the end.
