• Fix wrong loop condition which would often lead to heap underread.

• Fix wrong subkey string length calculation, which would result in an incorrect string being used to open an image specific key.

• Don't close the key handle in LdrQueryImageFileKeyOption() because it's used more than once and closed after it's not needed anymore.

• Use Zw* functions instead of Nt* where necessary in LdrQueryImageFileKeyOption().

• Per-image execution options work now (e.g. enabling DPH).
