tools/bootconfig: Remove unneeded error message silencer

Browse Source 
Remove error message silent knob, we don't need it anymore
because we can check if there is a bootconfig by checking
the magic word.
If there is a magic word, but failed to load a bootconfig
from initrd, there is a real problem.
