drm/xe/vf: Avoid reading media version when media GT is disabled
When the media GT is not allowed, a VF must not attempt to read
the media version from the GuC. The GuC may not be loaded, and
any attempt to communicate with it would result in a timeout
and a VF probe failure:
(...)
[ 1912.406046] xe 0000:01:00.1: [drm] *ERROR* Tile0: GT1: GuC mmio request 0x5507: no reply 0x5507
[ 1912.407277] xe 0000:01:00.1: [drm] *ERROR* Tile0: GT1: [GUC COMMUNICATION] MMIO send failed (-ETIMEDOUT)
[ 1912.408689] xe 0000:01:00.1: [drm] *ERROR* VF: Tile0: GT1: Failed to reset GuC state (-ETIMEDOUT)
[ 1912.413986] xe 0000:01:00.1: probe with driver xe failed with error -110
Let's skip reading the media version for VFs when the media GT is not
allowed.
v2: move the condition directly to the VF path
