Gustavo Pimentel 84b0aa2e0d dmaengine: dw-edma: Add pcim_iomap_table return check
Currently, is missing a null check on a pcim_iomap_table() return value
and this can lead to a null pointer dereference if the desired BAR
wasn't mapped previously.
Fix this by adding a null check and returning -ENOMEM.
