After loading the module with load failure injection enabled don't try check the alive state. Also limit the number of failure points to existing ones, to reduce the run time of the test. v2: - make VT binding/snd module loading part of reload and VT bind fail silently (Chris) Signed-off-by: Imre Deak <imre.deak@intel.com>
