sb/intel/lynxpoint/pcie.c: Add more checks for NULL pointers
If PCIe root port `n` is disabled, then `rpc.ports[n - 1]` remains NULL.
The existing Lynx Point systems probably don't end up dereferencing
NULL pointers this way. However, it might occur on a system using
Flexible I/O to remap PCIe root ports to other functions.
Tested on an ASRock H81M-HDS and an Acer C720 (Google Peppy). No issues
presented themselves.
