aer: impove pcie_aer_init to support vfio device

Browse source 
pcie_aer_init was used to emulate an aer capability for pcie device,
but for vfio device, the aer config space size is mutable and is not
always equal to PCI_ERR_SIZEOF(0x48). it depends on where the TLP Prefix
register required, so here we add a size argument.
