Subject: [PATCH] x86/PCI: Increase info->res_num before checking pci_use_crs
We should increase info->res_num before we checking pci_use_crs return
when pci=nocrs set.
No functional change, since we don't use res_num and res_offset[]
in the "!pci_use_crs" case anyway, but this makes the code read better.
