Todd Broch 84e85bd6f0 pd: Qualify modep pointer before use. ...

If UFP sends invalid VDM responses to the DFP its possible that modep
pointer may be NULL.  CL qualifies all uses of modep to guarantee that
these invalid responses don't cause samus_pd to crash.

BRANCH=samus
BUG=chromium:476773
TEST=manual,
1. Still successfully negotiate alternate mode (both DP & GFU) with
   hoho.
2. passes usbpd_DisplayPortSink autotest.
