staging: comedi: addi_apci_3xxx: check return value
Function pci_ioremap_bar() will return a NULL pointer if there is no
enough memory. However, in function apci3xxx_auto_attach(), the return
value of function pci_ioremap_bar() is not validated. This may result in
NULL dereference in following access to dev->mmio. This patch fixes the
bug.
