In hash autotest, the size of tables that should be succesfully created
is 32K entries (256KB), except for the table called "different_name",
which is 1M entries (8MB). When memory is too fragmented (with 2M
hugepages), the test can fail.
To avoid allocation failures due to memory fragmentation, decrease the
size of the table to 32K.
