drm/i915/gt: Clear CACHE_MODE prior to clearing residuals
Since we do a bare context switch with no restore, the clear residual
kernel runs on dirty state, and we must be careful to avoid executing
with bad state from context registers inherited from a malicious client.
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/2955
Fixes: 09aa9e45863e ("drm/i915/gt: Restore clear-residual mitigations for Ivybridge, Baytrail")
Testcase: igt/gem_ctx_isolation # ivb,vlv
