Subject: [PATCH v4 1/5] PCI/AER: Remove redundant pci_is_pcie() checks.

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>

AER is a PCIe Extended Capability. So checking for dev->aer_cap
will implicitly include check for PCIe device. So remove redundant
pci_is_pcie() checks.
