Hash :ccee686a Message :ztex: precheck the secondary solutions to avoid hw errors
the ztex bitstreams gives back the latest checked nonce and
its hash7 value and two possible solutions.
every 250ms the latest nonce is checked and compared with hash7
to count hw errors and adapt the MHz value. one change is to
use the solutions even if the latest nonce is not correct. the
original java ztex code also does it this way.
since the second solution is often not correct we have alot
of hw errors. now we always check the second solution before
we submit it to the cgminer main code.
the java code also ignores all hw errors 500ms after a sendHash.
we now do the same. this can possibly yield in a higher MHz rate.
but the chance is so low nobody will ever notice in practice.
