Allan Jude 11ba8488b8 iicsmb: Request the bus recursively in bread()
ipmi_ssif will `smbus_request_bus()` to do multiple smbus requests
(which requests the iicbus), and then here in `bread()` we also need to
request the bus because `bread()` takes multiple transactions.
This causes deadlock as it's waiting for the bus it already has without
`IIC_RECURSIVE`.
