drm/i915/gem: Do not leak siblings[] on proto context error
Description
In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Do not leak siblings[] on proto context error After a successful BALANCE/PARALLEL_SUBMIT extension on context creation, error during processing of next user extension leaks the siblings[] array. Fix that. Discovered using AI-assisted static analysis confirmed by Intel Product Security. (cherry picked from commit aa65e0a4b51b3b54b53e4142aaa2d997aa1061ff)
