kfdtest: Disable host access for VRAM

KFDExceptionTest.SdmaQueueException allocates VRAM with host access. This
fails on small-BAR GPUs. This error was incorrectly ignored before
412b24137e ("kfdtest: Full TearDown and SetUp in child process").

The test doesn't really need host access to the memory. Therefore the fix
is to disable the HostAccess flag.
