If we could not mount the real root device, or the init program did not exist on it, bail out instead of panicing

In these cases, we will exec /bin/sh, such that manual recovery is still possible as sh has PID 1
An expert might be able to mount and switch_root manually. In any case, this is less scary than a panic and a useless trace.
