tg3: Move per-int rx members to per-int struct

This patch moves the rx_rcb, rx_rcb_mapping, and rx_rcb_ptr return ring
device members to a per-interrupt structure.  It also adds a new return
ring consumer mailbox register member (consmbox) and converts the code
to use it rather than a preprocessor constant.
