msm: mdss: check intr line status before handling isr
Hardware might return/call the pending interrupt
on one CPU when same interrupt is disabled from other
core. Such parallel processing may lead to unclocked
register access in interrupt context followed by
panic. It is safe to check the interrupt line status
before handling isr to avoid crash in such race
condition.
