Bugs Fixed

• For NDB tables having no explicit primary key, NdbReceiverBuffer could be allocated with too small a size. This was due to the fact that the attribute bitmap sent to NDB from the data nodes always includes the primary key. The extra space required for hidden primary keys is now taken into consideration in such cases. (Bug #30183466)
