[Intel-gfx] [PATCH i-g-t] igt/drv_missed_irq: Skip if the kernel reports no rings available to test

> Some setups (e.g. guc and gen10+) can not disable the MI_USER_INTERRUPT
> generation and so can not simulate missed interrupts. These tests would
> fail, so skip when the kernel reports no tests available.
