Brian Smith d279a21d8c Avoid potential uninitialized memory read in crypto/ec/p256-x86_64.c.
If the function returns early due to an error, then the coordinates of the
result will have their |top| value set to a value beyond what has actually
been been written. Fix that, and make it easier to avoid such issues in the
future by refactoring the code.

As a bonus, avoid a false positive MSVC 64-bit opt build "potentially
uninitialized value used" warning.
