Fix a CHECK when monitor configuration changes
This fix is specific to GPU V-sync configuration (e.g. running
Chrome with --enable-features=D3DVsync switch).
When monitor configuration changes GetMonitorInfo returns FALSE and
the output data remains uninitialized. In this case GpuVSyncProvider
will use a backup delay based v-sync mechanism.
It looks a similar problem might exist in a general case as well.
I am going to address it separately.
