Addresses regressions from the reverted merge of the tbx fault manager for host memory. This fixes attempts by the tbx fault manager to protect/unprotect host buffer memory, even if the host ptr was not driver-allocated. In the case of the smoke test that triggered the critical regression, clCreateBuffer was called with the CL_MEM_USE_HOST_PTR flag. The subsequent `mprotect` calls on the provided host ptr then failed. Related-To: NEO-12268 Signed-off-by: Jack Myers <jack.myers@intel.com>
