IB/ipath: Prevent random program use of diags interface
To prevent random utility reads and writes of the diag interface to the
chip, we first require a handshake of reading from offset 0 and writing
to offset 0 before any other reads or writes can be done through the
diags device. Otherwise chip errors can be triggered.
