Apply DMA address space restriction to controllers that have 4GB

observed on BCM5704 which lives behind certain PCI-X bridge(e.g.
AMD 8131 PCI-X bridge). It's still not clear whether the root
cause came from that PCI-X bridge or not. The watchdog timeout
indicates the issue is in TX path. If the bridge reorders TX
mailbox write accesses it would generate all kinds of problems but
I'm not sure. This should be revisited.

Make sure to always do source address selection on

If an address is specified via a multicast option, then
let it override normal the source address selection.
This fixes a bug where source address selection was
not being performed when multicast options were present
but without an interface being specified.
Move the increment operation under the lock and split the condition
