PCI: fix search for suitable memory region

Binary ANDing a value with 0 and comparing it against 0 always yields true, I guess that's not intended here.
Use the proper mask value for the memory region type bit.

See commit 3526285068598f4e2ddaf19d4bd94f253de06ce9 "pci: fix checking PCI_REGION_MEM in pci_hose_phys_to_bus()" which is already in the mainline.
