drm/i915/perf: fix gen11 engine class shift
Use the correct engine class shift value while storing the ctx hw id.
Fixes the copy+paste error from commit 61d5676b5561 ("drm/i915/perf: fix
ctx_id read with GuC & ICL").
Apologies for not spotting this in the original review, the
specific_ctx_id_mask is correct, only the specific_ctx_id had this
problem.
v2: Just use the upper 32 bits of lrc_desc (Chris)
v3: If we use the lrc_desc, we must apply the ctx_id_mask too (Lionel)
Fixes: 61d5676b5561 ("drm/i915/perf: fix ctx_id read with GuC & ICL")
