test: temporal disable negtive test for VAEntrypointEncSliceLP

from intel MTL+, there are only one entry point for encode: VAEnctrypointEncSlice
to avoid some potential issue: some application dose not call query before use
entrypoint, and only use VAEnctrypointEncSliceLP.
so there are one WA to accept both VAEnctrypointEncSlice & VAEnctrypointEncSliceLP
even only report VAEnctrypointEncSlice in vaQueryConfigEntrypoint
