r8117: fixed a bunch more dos error code handing.

The biggest change was fixing the RAW-CONTEXT test. It was forcing
capabilities to zero in an attempt to not negotiated extended
security, but as a side effect it was forcing negotiation of dos error
codes. This confused the hell out of the test code!

Also fixed a bunch of places incorrectly using NT_STATUS_V() instead
of NT_STATUS_EQUAL() and several places that had the wrong dos status
codes
