Use pci_resource_name() helper in pdev_sort_resources() to print
resources in user-friendly format. Also replace the vague "bogus
alignment" with a more precise explanation of the problem.

v2:
- Place colon after %s %pR to be consistent with other printouts
- Replace vague "bogus alignment" with the exact cause

Why bother with local variable if only used here?
Absolutely fine if you have more code coming that uses it again though!

Otherwise seems sensible change.

Fair enough. local style is perfectly valid reasoning.
