Bug#4586 + TC fix

ndb/src/kernel/blocks/dbtc/DbtcMain.cpp:
  Operations with marker always leads to abort even
  if IgnoreError was supplied (limitation)
  
  Check marker before marking operation as aborted (which removes marker)
ndb/src/kernel/blocks/dbtup/DbtupPagMan.cpp:
  Init cnoOfAllocatedPages after returnCommonArea
