staging: gpib: Add return value to request_control
A number of drivers are unable to release control due to hardware or
software limitations. As request_system_control was defined as void,
no error could be signalled.
This patch changes the prototype of request_system_control to int and
adds the appropriate checking and returns. In the case that a board
cannot release control EINVAL is returned. If a driver does not
implement request_system_control EPERM is returned.
