[Intel-wired-lan] [PATCH S24 12/12] ice: Add input handlers for virtual channel handlers

From: "Amruth G.P" <amruth.gouda.parameshwarappa at intel.com>
Move the assignment to local variables after validation.
Remove unnecessary checks in ice_vc_process_vf_msg() as the respective
functions are now performing the checks.
