The 'use pci_find_ext_capability everywhere' cleanup brought a new bug, which makes the AER stop working. Fix it by actually using find_ext_cap instead of just find_cap. Drop the unused config space size define while we're at it. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
