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

... 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.
