PCI: acpiphp_ibm: Fix null dereferences on null ibm_slot
ibm_slot_from_id() can return null if the des header signature is not
"aPCI" or if the kmalloc() for the return ACPI descriptor fails, causing
potential null pointer dereferences on the return null descriptor.
Handle the null case with appropriate check and error return.
