Atish Patra ff2ca5439c riscv: Trace irq on only interrupt is enabled 
commit 7cd1af107a92eb63b93a96dc07406dcbc5269436 upstream.

We should call irq trace only if interrupt is going to be enabled during
excecption handling. Otherwise, it results in following warning during
boot with lock debugging enabled.
