or1k: Correct longjmp return value
Invert equality check instruction to correct the return value handling
in longjmp.
The return value should be the value of the second argument to longjmp,
unless the argument value was 0 in which case it should be 1.
Previously, longjmp would set return value 1 if the second argument was
non-zero, and 0 if it was 0, which was incorrect.
