This doesn't seem like the right place. What you really should do is skip calling ehci_silence_controller() if the hardware isn't accessible. That's where the hardware gets touched, not in ehci_shutdown().
Just tried this suggestion, this would not work as well, Its not just the hardware registers, which are of concern here, but also the rest of the things like ehci->hrtimer pointer which are allocated or initialized as part of ehci_setup().
Either the msm controller driver is not correct or we should have a way to stop calling ehci_shutdown() if there was no ehci_setup() done yet.
