Description:
In function 'sendStopMgmd' the create mgm handle will not be freed if an error is found
in the function. For example if connect to mgmd fails, call of 'ndb_mgm_stop' fails of if
'ndb_mgm_restart2' fails.

How to repeat:
valgrind, MCI

Suggested fix:
Add calls to 'ndb_mgm_destroy_handle'
