6rd: Clear correct IPv6 address bits in 6rdcalc
The correct bits are now cleared in the IPv6 address as the shift value to the correct byte in the IPv6 address was wrong. Depending on the stack values this could result in a hanging 6rdcalc program due to an endless loop. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> SVN-Revision: 38818
