igt/drv_module_reload: Revamp fault-injection

The current method of checking for a failed module load is flawed, as we
only report the error on probing it is not being reported back by
modprobe. So we have to dig inside the module_parameters while the
module is still loaded to discover the error.

v2: Expect i915.inject_load_failure to be zero on success
v3: Do a full i915 unload to ensure fbdev is unbound in cases where it
managed to bind itself before failure injection.
