Ramil Kalimullin 06be03f77c Fix for bug#49465: valgrind warnings and incorrect live checksum... ...

Problem: inserting a record we don't set unused null bits in the
record buffer if no default field values used.
That may lead to wrong live checksum calculation.

Fix: set unused null bits in the record buffer in such cases.

  Fix for bug#49465: valgrind warnings and incorrect live checksum...
    - set unused null bits to 1 in the record buffer in case we
  don't call restore_record() before a fill_record() call
  (when no default values used).
