BUG#26325 - TEMPORARY TABLE "corrupt" after first read, according 

            to CHECK TABLE

CHECK/REPAIR TABLE reports "File not found" error when issued
against temporary table.

Fixed by disabling a brunch of code (in case it gets temporary table)
that is responsible for updating frm version as it is not needed
for temporary tables.
