bn/asm/ppc-mont.pl: signal no-op in 32-bit bit build.

Browse Source 
The bug was introduced in 80d27cdb84,
one too many instructions was removed. It went unnoticed, because
new subroutine introduced in previous commit is called in real-life
RSA/DSA/DH cases, while original code is called only in rare tests.
The bug was caught in test_fuzz.
