Try to fix PS3 save state issue.

In the past while fixing state problems i Wii, this section was the last one i found to be a problem as well. Ignoring this state variable fixes the last Wii state loading problem. PS3 has recently been reported as having state problems and could be similar issue. So, lets just ignore this state variable for all big-endian platforms.
