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.
Addresses-Coverity: ("Dereference null return")
