Bug #49782 ndb_mgm client does not report data memory decreased

Description:
When data memory is full and then decreased and the ndb_mgm client is running there should be the following message:

2009-12-17 19:35:07 [MgmSrvr] INFO     -- Node 2: Data usage decreased to 15%(5 32K pages of total 32)

This works in 6.3 but not in 7.0 (tested 7.0.6 and 7.0.9)

How to repeat:
1. Run ndb_mgm
2. Fill data memory
3. TRUNCATE TABLE t1;

This is a regression.

Fixed by the patch for BUG#31542, see below test protocol.

mysql> use test
