  bug #22372 (LOAD DATA crashes the table with the GEOMETRY field)
  
  The problem is that the GEOMETRY field doesn't have and default value
  that is usually set by Field::reset method, if the field can't be NULL.
  So if the loaded file doesn't have all the data it can't be loaded.
  
  I propose to check if the 'reset' operation is possible for the field
  and return an error if it's not.

    if the field can't do the 'reset' operation properly we can't execute further
