Description:
In the ha_ndbcluster::open method
the share object isn't released in all error
situations.

How to repeat:
Hard to repeat, found by code inspection

Suggested fix:
Release all resources in all error situations in ::open call

I don't fully understand ... the only preliminary return
after successfull m_share allocation does free it,
not sure though whether the main code path should 
also free it on certain values of res?

If either get_metadata or get_ndb_statistics fails the method will return an error and keep the share
object.
