[ofa-general] Current list of Linux maintainers and their email info

[Roland Dreier]

thanks Sean.

I notice at least CXGB3 is missing from MAINTAINERS -- Steve, if you
want to send an entry I would add it.

Also if anyone wants to add an ISER entry that would be good too.

I could add IP-OVER-INFINIBAND and SRP entries but not sure it's worth
it since I'm already in the main INFINIBAND entry.

Maybe it's worth changing "INFINIBAND SUBSYSTEM" to
"INFINIBAND/IWARP/RDMA SUBSYSTEM"?
