drm/i915: Fix __gen125_emit_bb_start() without WA

Browse source

ce->wa_bb_page is allocated only for graphics version 12. However
__gen125_emit_bb_start() is used for any graphics version >= 12.50. For
the currently supported platforms this is not an issue, but for future
ones there's a mismatch causing the jump to
`wa_offset + DG2_PREDICATE_RESULT_BB` to be invalid since wa_offset is
not correct.

As in other places in the driver, check for graphics version "greater or
equal" to future-proof the support for new platforms.
