commit e522a712 upstream.

The following patch sets the MaxPayload setting to match the parent
reading when inserting a PCIE card into a hotplug slot.  On our system,
the upstream bridge is set to 256, but when inserting a card, the card
setting defaults to 128.  As soon as I/O is performed to the card it
starts receiving errors since the payload size is too small.
