scsi: ufs: core: Avoid IRQ thread wakeup during active UIC command

Browse source

Only return IRQ_WAKE_THREAD when MCQ and ESI are not enabled and no UIC
command is active. The default UIC command timeout is 500ms, Using threaded
IRQs during an active UIC command increases the risk of timeout due to
possible preemption by other system IRQs.
