What type of PR is this?
/kind bug

What this PR does / why we need it:
Currently if we fail to create a snapshot in a CSIFinalError way, the error is overwritten when we attempt to remove the annotation on the content. This can result in the snapshot controller logging the error, but subsequent logs (and events) being nil:

I0420 18:59:30.106430 1 snapshot_controller.go:301] createSnapshotWrapper: CreateSnapshot for content snapcontent-5e494f19-ea35-480c-89f8-626e6ad1dbd3 returned error: rpc error: code = Unknown desc = AzureDisk - invalid option invalid in VolumeSnapshotClass
...
E0420 18:59:30.506775 1 snapshot_controller.go:105] createSnapshot for content [snapcontent-5e494f19-ea35-480c-89f8-626e6ad1dbd3]: error occurred in createSnapshotWrapper: failed to take snapshot of the volume, ...%!q()

We don't see any Events with the correct error logged. By changing the error we're able to get the events correctly created. There are still periodic issues with stale resources, but these are addressed by changing to Patch (or by performing a Get in updateContentErrorStatusWithEvent). These changes are being made in #480 , and therefore I didn't include them here.

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

VolumeSnapshotContent creation errors can now propagate to the appropriate VolumeSnapshotContent resource.
