drm/xe/mocs: Initialize MOCS index early
commit 2a58b21adee3df10ca6f4491af965c4890d2d8e3 upstream.
MOCS uc_index is used even before it is initialized in the following
callstack
guc_prepare_xfer()
__xe_guc_upload()
xe_guc_min_load_for_hwconfig()
xe_uc_init_hwconfig()
xe_gt_init_hwconfig()
Do MOCS index initialization earlier in the device probe.
