descrypt-opencl per-salt kernels optimization 4096 limit is not working properly

I created the test case for i in `seq 1 95000`; do mkpasswd -m des asd$i; done > ~/testdes.in

See #2655.

Reproduce the issue with the provided mkpasswd loop and inspect the stack trace through bt.c:create_tables and create_perfect_hash_table, then opencl_DES_bs_plug.c:fill_buffer/build_tables and opencl_DES_bs_h_plug.c:reset. Compare the behavior with issue #2655 and verify that the 4096-limit handling works correctly for the 95,000 generated DES hashes.
