vboot: Remove LoadKernel() LBA size/count checks

Browse Source 
Now that LoadKernel() uses a stream API for its partition data, it
doesn't care about those fields.  They're blindly passed to
cgptlib_internal, which does similar checks in CheckParameters() and
CheckHeader().  So, don't duplicate the checks.
