Kévin Petit 509172b780 cl20: Khronos Bug 16235: Allow the barrier test to pass in isolation (#262) ...

The input buffer to tests in execute_block suite is set to some
value (0xdeadbeef) but supposed to be reset in each test such
so that observing 0 after executing the test guarantees that
the status is that of the test and not a pre-existing value.

This commit adds missing initialisation to block_barrier kernel code
and removes an extra redundant barrier at the end.

This test is the last in the suite. After executing other tests the
input/output buffer is not being reset on a host side and therefore
running the test after successful execution of the previous test
(resulting in writing expected 0 into the buffer) was hiding the
problem.
