drm/i915/gt: Fix NULL deref on sched_engine alloc failure

Avoid using intel_context_put() before intel_context_init() in execlists_create_virtual() as the kref_put() inside would lead to NULL deref on the IOCTL path when sched_engine allocation fails.

Discovered using AI-assisted static analysis confirmed by Intel Product Security.
