The check whether GuC ABI version meets requirements shall be
performed after said version is received from GuC.
Doing it in wrong order was triggering a warning:
xe 0000:00:02.1: [drm] Assertion `gt->sriov.vf.guc_version.major` failed!
With this change, dislodge part of the VF migration support check
and moved it to after GuC handshake.
