    PCI/AER: Factor out HEST device type matching
    
    This factors out the matching of HEST structure type and PCIe device type
    to improve readability.  No functional change.

    PCI/AER: Set dev->__aer_firmware_first only for matching devices
    
    Previously, we always updated info->firmware_first, even for HEST entries
    that didn't match the device.  Therefore, if the last HEST descriptor was
    a PCIe structure that didn't match the device, we always cleared
    dev->__aer_firmware_first.
