Avoid copying of NormalizedKernelFunc temporary instance

Coverity analysis of IntelPython/dpctl.git SYCL-based projects shows
6721 hits of COPY_INSTEAD_OF_MOVE type issues in ResetHostKernelHelper
with the suggestion to use std::move(NormalizedKernelFunc) instead.

This PR applies that suggestion.
