drv_module_reload_basic: skip alive check after load failure injection

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
