PNP: skip dev->protocol NULL checks

[Bjorn Helgaas]

Every PNP device should have a valid protocol pointer.  If it doesn't,
something's wrong and we should oops so we can find and fix the problem.

[This fixes a Coverity warning, but does not need to be in 2.6.25.
I'd rather have it in -mm for a while and put it in 2.6.26.]
