    drm/i915: Call i915_perf_fini() on init_hw error unwind

    We have to cleanup after i915_perf_init(), even on the error path, as it
    passes a pointer into the module to the sysfs core. If we fail to
    unregister the sysctl table, we leave a dangling pointer which then may
    explode anytime later.

    Fixes: 9f9b2792b6d3 ("drm/i915/perf: reuse timestamp frequency from device
info")

It's hard to be sure since it causes memcorruption and dies in various ways on
subsequent tests.
