Subject: [PATCH] i2c: aspeed: Fix the dummy irq expected print

When the i2c error condition occurred and master state was not idle,
the master irq function will goto complete state without any other
interrupt handling. It would cause dummy irq expected print. Under
this condition, assign the irq_status into irq_handle.
