row_sel_store_mysql_rec(): Convert NULL true VARCHAR columns

Browse source 
correctly.


innobase/row/row0sel.c:
  Initialize NULL true VARCHAR columns with NUL bytes, as that is
  what the columns will contain in handler::write_row().  (Bug #12186)
mysql-test/r/innodb.result:
  Update table checksums to reflect the new handling of
  true VARCHAR columns that are NULL.
