dmaengine: ipu: Make sure the interrupt routine checks all interrupts.

Browse source 
commit adee40b265d7568296e218f079f478197ffa15bf upstream.

Commit 3d8cc00073 ("dmaengine: ipu: Consolidate duplicated irq handlers")
consolidated the two interrupts routines into one, but the remaining
interrupt routine only checks the status of the error interrupts, not the
normal interrupts.

This patch fixes that problem (tested on i.MX31 PDK board).
