PCI: pcie, aer: init struct aer_err_info for reuse

In case of multiple errors, struct aer_err_info would be reused among
all reported devices.  So the info->status should be initialized before
recycled.  Otherwise error of one device might be reported as the error
of another device.  Also info->flags has similar problem on reporting
TLP header.
