drm/i915/perf: use the lrc_desc to get the ctx hw id in gen8-10
The upper 32 bits of the lrc_desc (bits 52-32 to be precise) are the
context hw id in GEN8-10, so use them and have one less thing to
maintain in the unlikely case we change the descriptor sw fields.
v2: If we use the lrc_desc, we must apply the ctx_id_mask too (Lionel)
