drm/i915/gt: Protect against overflow in active_engine()
It is unlikely, but possible for the first call to
intel_context_create() to fail with -ENOMEM, which would result
in entering the following code block and decrementing "count",
when it is set to 0 (initial condition in the for loop).
Protect from overflowing the variable by checking for 0 value
of "count" before entering the loop.
