Russell Currey e6cd4f09b4 powerpc/eeh: Null check uses of eeh_pe_bus_get ...

commit 04fec21c06 upstream.

eeh_pe_bus_get() can return NULL if a PCI bus isn't found for a given PE.
Some callers don't check this, and can cause a null pointer dereference
under certain circumstances.

Fix this by checking NULL everywhere eeh_pe_bus_get() is called.
