msm: mdss: Change function from disbale_irq_nosync to disbale_irq

Potential deadlock can happen while we disable irq and at the same
time an irq is triggered to request for the same resource. Thus,
it will pre-empt the spin-lock. Hence, change the function call to
disbale_irq to prevent local interrupts.
