bug #22372 (LOAD DATA crashes the table with the geometry field) 

The problem is that the GEOMETRY NOT NULL can't automatically set
any value as a default one. We always tried to complete LOAD DATA
command even if there's not enough data in file. That doesn't work
for GEOMETRY NOT NULL. Now Field_*::reset() returns an error sign
and it's checked in mysql_load()


mysql-test/r/gis.result:
  test result
mysql-test/t/gis.test:
  testcase
sql/field.cc:
  reset() now returns error sign
sql/field.h:
  Field_*::reset() now returns error sign if the field can't be reset
sql/sql_load.cc:
  check if field can't be reset and return error if it's so
