    x86/boot/32: Flip the logic in test_wp_bit() · 952a6c2c

    ... to have a natural "likely()" in the code flow and thus have the
    success case with a branch 99.999% of the times non-taken and function
    return code following it instead of jumping to it each time.
    
    This puts the panic() call at the end of the function - it is going to
    be practically unreachable anyway.
    
    The C code is a bit more readable too.
    
    No functionality change.
