[win-pv-devel] [PATCH] Remove ZwFlushKey() from registry code

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

Attempting to flush registry keys early in boot causes an error to be
logged.

This patch therefore removes the explicit flushes from the registry code.
There is no option but to trust Windows lazy flush.
