drm/i915/guc: Debug print LRC state entries only if the context is pinned
After the context is unpinned the backing memory can also be unpinned,
so any accesses via the lrc_reg_state pointer can end up in unmapped
memory. To avoid that, make sure to only access that memory if the
context is pinned when printing its info.
v2: fix newline alignment
