Dropped weight from lfsr_rbyd_fetchvalidate

Browse Source 
We really only rely on cksum here.

Passing weight was useful for an assert, but it clutters up the function
call with a parameter that isn't used normally.

Removing ths saves a bit of code:

           code          stack
  before: 33670           2592
  after:  33654 (-0.0%)   2592 (+0.0%)
