x86/traps, context_tracking: Assert that we're in CONTEXT_KERNEL in exception entries

Other than the super-atomic exception entries, all exception
entries are supposed to switch our context tracking state to
CONTEXT_KERNEL. Assert that they do.  These assertions appear
trivial at this point, as exception_enter() is the function
responsible for switching context, but I'm planning on reworking
x86's exception context tracking, and these assertions will help
make sure that all of this code keeps working.
