[i915-rt v6 17/24] drm/i915: Drop the irqs_disabled() check

[Maarten Lankhorst <dev@lankhorst.se>]

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

The !irqs_disabled() check triggers on PREEMPT_RT even with
i915_sched_engine::lock acquired. The reason is the lock is transformed
into a sleeping lock on PREEMPT_RT and does not disable interrupts.

There is no need to check for disabled interrupts. The lockdep
annotation below already check if the lock has been acquired by the
caller and will yell if the interrupts are not disabled.

Remove the !irqs_disabled() check.
