iavf: Fix return values in driver

Several functions in the iAVF core files take status values of the enum iavf_status and convert them into integer values. This leads to confusion as functions return both Linux errno values and status codes intermixed.Fix this by introducing iavf_status_to_errno, a switch that explicitly converts from the status codes into an appropriate error value.
